Introduction

With the innovation wave of intelligent technology, more and more intelligent products begin to enter people's vision and quietly change our quality of life. As a new element in the wearable field, the smart bracelet has become an indispensable equipment in life and work with the continuous development and innovation of technology in the past two years. Whether it's high-end bracelets worth thousands of yuan or products worth dozens of yuan, they are emerging in the market one after another, but most of them remain in the basic functions such as measuring steps, monitoring sleep quality, and at the same time, they need to use mobile apps to display data results. How to choose a smart bracelet that is both easy to operate and excellent in performance has become a topic of discussion among consumers.

The Hesvitband S3 smart bracelet presented to you today is not only able to measure the number of exercise steps, but also a high-tech product integrating the measurement functions of heat consumption, heart rate monitoring, wrist temperature and humidity, air pressure and so on. In addition, the biggest highlight of this smart bracelet is that it uses the world's first full screen display technology. It does not need to use the mobile phone screen or switch the interface, and all the measurement results can be clearly presented to users. This is a smart bracelet that focuses on the health route. What's the magic about it? Let's start today's evaluation journey together with the editor.

Open box display

The bracelet is packed in a relatively rare transparent plastic sheet box. At first glance, it seems that the quality is somewhat low. For such a powerful product, it is recommended to use a gift box with more beautiful visual effects for packaging, which can give users a good initial impression.

The packaging box is easy to be pierced to the skin by the hard plastic plate during the opening process, and the unpacking experience is poor. A user manual is built in the box, and the logo of "Hesvit" is marked on the upper surface; The pattern of two small green leaves interlacing together is very pleasing, highlighting the product theme and caring for the health of users.

Similar to the packaging of quartz watches and mechanical watches on the market, the bracelet is fixed on it through a support frame. Compared with the simple outer packaging, it still looks very high-end. The shape and structure of the bracket match the shape of the wrist strap of the bracelet very well. You only need to gently remove it from the top, instead of unfastening the wrist strap.

Apart from a simple instruction manual, there are no other accessories. You may wonder why there is no charging data cable? Because the charger interface of this bracelet is the same as the USB interface of ordinary mobile phones, it simplifies accessories and reduces costs, which is worth advocating. The manual guide explains the operation methods and functions of the bracelet. You must read it carefully before using it. After all, this Hesvit smart bracelet is rarely touched by us at ordinary times, and there are many functions and features we are not familiar with.

The front and back of the bracelet are displayed. In order to facilitate people to better understand this product, the editor summarizes the main parameters as follows:

Product name: Hesvitband S3

Sensors: heart rate, three-axis accelerator, body surface temperature, temperature and humidity, air pressure

Data synchronization: low-power Bluetooth 4.0 data synchronization

Screen specification: LCD，17*21mm

Hesvit The smart bracelet adopts the design scheme of the whole body in one color, with a unique rectangular display design instead of the stereotyped round chip particles. The bold attempt has made users more popular. The drawback is that the integrated design of the wrist strap and the screen cannot be separated, which also means that it is impossible to change the wrist strap of different colors according to your mood. After reading the unpacking introduction, let's take a closer look at the details of the bracelet.

Detail display

The front of the bracelet is an LCD display with nine layers of backlight, which can display all the monitored data, including the traditional time, power, walking steps, walking mileage, heat consumption and sleep duration display; It also adds more high-tech heart rate measurement, wrist temperature and humidity, watch skin temperature, and atmospheric pressure numerical display. The bracelet adopts such a unique one screen display technology, which breaks the traditional display mode with mobile phones and can bring users a better viewing experience.

The heart-shaped button at the bottom of the screen is the only control button of the bracelet. Press briefly to turn on the screen backlight; Press and hold for 2-6 seconds to turn on or off the heart rate test; Press and hold for more than 10 seconds and the clock flashes, then press and hold for a short time to adjust the time. The multifunctional keys give users a convenient experience in terms of operability, but Xiaobian feels that the touch touch of keys is lacking and relatively stiff, which needs further improvement.

Hesvit The bracelet collects blood flow data through optical sensors, and then carries out a series of core algorithms to get the numerical results we need; The green light source module can measure the heart rate. This module is composed of two green wavelength light-emitting LEDs and a photosensitive sensor. Its principle is based on the fact that the blood in the arm blood vessels will change in density when pulsing, resulting in changes in light transmittance. It can continuously measure the heart rate, calculate the average heart rate, record the maximum heart rate, etc. The white metal point below is a temperature sensor, which can detect the temperature of the watch skin.

The bracelet uses the traditional Micro USB interface for charging connection, and the slender rotating cover plate on the interface surface more or less affects the overall beauty of the bracelet. The process of pulling out or inserting is very laborious each time. It is difficult to pull out if the plug is too tight, and it is easy to fall off if the plug is loose. Xiao Bian thinks that the metal contact connection charging mode adopted by many bracelets and watches is very good, which is convenient and beautiful.

The wrist strap is made of TPU, and the buckle is made of metal. At the same time, several fixing holes are designed on the wrist strap, which can freely adjust the tightness of the wrist strap; The clip on the wrist strap can slide freely, which is convenient for fixing the extended part. The surface of the wrist strap is designed in a special pattern, which is very comfortable to feel; There is also a relatively obvious horizontal structure inside, which increases the friction with the skin and ensures the stability of the bracelet during data acquisition and measurement.

The inflection point connecting the bracelet measurement display module and the wrist strap is very hard, and the overall radian is consistent with the structure of the human wrist; It is suitable for most boys with thick wrists to wear this bracelet, but for girls with relatively thin wrists, the gap between the two sides is large when wearing it, which makes it bulky.

user's experience

Short press of the function key during the use of the bracelet can light up the backlight of the display screen, so that the measurement data can be observed more clearly at night or in the dark environment; The white LED light is very soft, and the eyes will not have uncomfortable symptoms. In addition, in case of abnormal heart rate and large temperature difference, LED light can flash for prompt, which is more intelligent.

Hesvit The actual wearing effect of the smart bracelet shows that for girls, if they want the bracelet measurement module to fully contact the skin surface, they need to slide up to the thicker part of the arm to ensure the accuracy of the measurement data. It is suggested that the module should be separated from the wrist strap, or the angle adjustment function should be added, so that people with different wrist thicknesses can wear it more comfortably.

Neither in the manual nor on the product website, there is no information about the battery power value of this bracelet. There is only an official 7-10 day standby time. Through personal tests in recent days, the bracelet can indeed last for about a week when it is fully charged. At the same time, the bracelet supports mobile power for charging and endurance, so you don't have to worry about being unable to use it even if you suddenly lose power during outdoor use. What is lacking is that during the charging process, there is only battery prompt, but no specific digital prompt; This is also true when the bracelet is used in standby mode. I hope that the subsequent system can support a digital viewing mode similar to that of mobile phone power.

Product Comparison

Next, we will compare several popular smart bracelets and watch devices in the market in many aspects. Of course, the purpose of the comparison is not to distinguish the good from the bad, but to let everyone have a deeper understanding of this Hesvit smart bracelet. The comparison products include the Xiaohei 2 watch, which is the main function of mobile phone message notification, the Xiaomi bracelet with simple and practical functions, and the 37 degree bracelet measured by the same health category. The functions and shapes of the four products all have their own characteristics, and the prices are quite different.

The wearing method of the small black watch is similar to that of the Hesvit bracelet, which is fixed by metal buckles; The 37 degree and millet bracelets use metal lugs to lock the wrist strap holes. Personally, Xiao Bian prefers the first two fixing methods. One is the style of a watch, and the other is that the latter often loosens. Comfort The small black watch and 37 degree wrist band are made of softer materials and have stronger affinity with the skin.

Although the functions of the small black watch and the Hesvit bracelet are very different, the same thing is that they both have their own display screens, which can directly produce data results without mobile devices. In addition to the basic time display and measurement of movement steps of the small black watch, Hesvit has many health measurement functions, which are its outstanding advantages. The small black watch is more inclined to the mobile phone message viewing and running training monitoring functions.

Even if the display screen is used, the small black watch supports the replacement of the wrist strap through a specific connection mode; The Hesvit smart bracelet may be designed as an integrated wrist strap with high airtightness in consideration of the special requirement that the measurement chip should not leak light. However, the overall experience effect is discounted, and the color and style of the wrist strap cannot be matched.

thirty-seven The function of the health bracelet is quite similar to that of Hesvit. In addition to the function of measuring steps, sleep quality and heart rate, 37 ° can also measure blood pressure, respiratory rate, mood and fatigue. In comparison, Hesvit also has several other special functions, such as temperature and humidity measurement, atmospheric pressure measurement. The biggest advantage is the intuitive integrated display screen, which is more practical. If the functions of the two bracelets are combined together, it must be more perfect. I especially think that Hesvit should add the function of white light blood pressure measurement. After all, blood pressure measurement is more important for users' health index evaluation.

The function of Xiaomi bracelet is relatively simple. Apart from the basic functions such as movement counting, sleep monitoring, and alarm of incoming calls, there are no special functions; However, the second generation light sensing version of Xiaomi bracelet came into the market recently, adding the function of heart rate measurement. It seems that this technology has become a necessity for bracelet products. Compared with Xiaomi bracelet, Hesvit smart bracelet has obvious advantages in terms of the type of detection items and display mode.

Finally, let's compare the charging methods of the four products. In addition to the Hesvit smart bracelet, the other three products are all connected to the auxiliary module through the metal PIN point for charging and endurance. This method has many advantages; In the first place, charging connection is more convenient and easy, and in the second place, it makes the product more beautiful. Therefore, I strongly suggest that the Hesvit bracelet also adopt this charging mode, and I believe users will like it more.

APP experience

As a smart bracelet, it not only supports the independent use of the device, but also can cooperate with the mobile app to obtain more experience modes. The app store searches for the "Hesvit bracelet" software to install it. After opening it, first enter the user's gender, age, height and other basic information.

Turn on the Bluetooth of the phone and close the bracelet to the phone to search and bind through the APP. After binding to the city, the software will automatically synchronize the various detection values stored in the bracelet. The bracelet can store data for 7-10 days. Users should pay attention to timely synchronization. We can see that the layout style of the APP main interface is very simple and clear, and each measurement item has corresponding icons and text descriptions, which are very intuitive.

Hesvit One of the highlights of the smart bracelet software is that it can bind and synchronize data even without logging in the account, but it can have more setting functions after logging in the account. The login method is convenient by registering a new account or WeChat.

After logging in, you can upload the historical data of the bracelet to the cloud for saving, and also share the measurement results to the third party platforms such as the circle of friends and QQ space to share the new experience of scientific life brought by the smart bracelet with everyone; In the help interface, you can view the binding method, function introduction and other instructions of the bracelet. No wonder there is no introduction in the manual, which was originally integrated into an electronic version.

Click the refresh button on the main interface to synchronize the bracelet measurement data at any time, and the value on the interface will be the same as that displayed on the bracelet screen. Some small partners may question whether this app is more than enough since they are all the same? What are the other functions? Let's continue to look down.

Each measurement data module can be clicked to view the detailed records, and each value can be recorded according to the grading statistics of the daily, weekly and monthly time periods, and the user can always understand the weekly and monthly exercise situation through the form of histogram and curve chart, just like a "sports coach" on the wrist to open a healthy exercise mode for life and move towards health.

The bracelet will automatically record the heart rate, wrist temperature and humidity, watch skin temperature and air pressure at the whole hour, thus generating a graph to indirectly provide health guidance for users. You can see that there is a large fluctuation in the writing curve in the picture. It is not the problem of measuring the bracelet, but that the bracelet is removed several times in the middle of the knitting process, resulting in abnormal data.

Each monitoring function is described in detail in the help options, which has certain guiding value for users; The small editor here specially explains that the Hesvit bracelet's accurate resting heart rate test technology is a highlight. The default automatic point test method, following the scientific method of human function law, maximizes the measurement standards, accuracy and humanized measurement design, and helps you monitor your heart rate during exercise or rest 24 hours a day.

Through the data stacking function, the user can stack many survey data together for observation, and the curve graphs generated by the similar data summary function can be compared and viewed. All the data of each hour are recorded in the icon, which can be viewed by sliding.

The bracelet has an intelligent reminder function, such as "ten thousand step reminder", "dressing reminder", etc. When the wearer's steps are monitored to exceed 10000, the bracelet screen will flash to prompt the user. When the user's hand skin temperature and wrist temperature are monitored to be 4 degrees different, the bracelet screen will also flash to prompt the wearer to increase or decrease clothing. The range of these values can be adjusted through setting options, which can be set by the user according to his own actual situation.

summary

As for this evaluation post on the Hesvitband S3 smart bracelet, the editor has brought so many things to you. There may be some things in the article that are not detailed or comprehensive. Please comment and correct more. In general, this bracelet has killed many similar products in the market because of its beautiful and simple appearance, intuitive one screen display and a variety of practical functions; However, during the evaluation process, Xiaobian also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of Xiaobian.

1、 The outer packing box of the product seems to be of a low grade. I hope it can improve the appearance style and texture of the package like the watch packing box.

2、 It is suggested that the measurement module of the bracelet be designed separately from the wrist strap, so that users can change the color of the wrist strap at any time according to their mood, and have a better wearing experience.

3、 The material of the bracelet and wrist strap is expected to be improved. At present, if you wear it for a long time, your skin will feel stiff. You can replace it with a softer material.

4、 The bracelet lacks edge adjustment structure, and girls with thinner wrists look awkward to wear. It is recommended to add adjustment function.

5、 Since heart rate measurement is available, why not add more practical blood pressure measurement function? In this way, users can know more about their own health index.

6、 It is hoped that the charging of the bracelet can be changed to the contact mode of the metal PIN pin, and the USB interface can be omitted to make the appearance of the bracelet more beautiful.

7. There is no description of important parameters such as the power and waterproof grade of the bracelet battery in the manual. It is suggested that it can be added later to facilitate users' use.
