The year 2016 is coming to an end. In the past year, intelligent wearable products have made another qualitative leap, especially in the aspect of smart bracelets, which have made new breakthroughs not only in function but also in appearance. Today, we bring you a smart bracelet, Ziva, which has just come into the market recently. First of all, thank you Love to play computer games Try to provide product experience opportunities, at the same time, thank the manufacturer for providing product support. Lexin bracelet ziva is a smart heart rate bracelet released by Lexin in 2016. It uses Italian imported calf leather wrist strap with fashionable metal body, and provides rose gold, champagne gold, and deep space gray colors to meet the daily matching needs. It can realize 24-hour continuous heart rate monitoring, automatically identify the movement mode, and at the same time, it has its own night mode, information reminder, sedentary reminder and other functions....

1、 Product unpacking:

The long-awaited bracelet was finally received. Before I could look at the outer package, I could not wait to open the package. Surprisingly, the outer package of the kraft paper box also contained a layer of colored boxes. The picture printed on the color inner package is the Lexin smart bracelet Ziva. This experience is more beautiful Tuhao gold.

The colorful inner packaging forms a sharp contrast with the outer packaging. The green inner packaging is as vibrant as the warm sun in winter. The outer package is printed with the LOGO of Lexin, with the words ziva on both sides, and the color information of the manufacturer and the bracelet on the back side.

The main color of the front of the inner package is green, the back is black, and the side is transparent plastic with a ziva bracelet. The special functions of ziva bracelet and relevant information of the product are printed on the inner package. Such double packaging can effectively prevent damage to the product in the process of logistics and transportation. It can be seen that Lexin is considerate of consumers from outside to inside.

To be honest, I fell in love with Ziva when I saw her at first sight. Not only its color, but also its overall appearance is incomparable to other smart bracelets. Ziva bracelet uses 0.87 inch OLED display screen with a resolution of 128 * 32PX. Ziva smart bracelet abandons the TPU wrist strap commonly used in bracelets and replaces it with Italian imported calfskin, which is more textured and comfortable to wear. It also uses a metal body and has the color of Tuhao gold, rose gold, etc. of mainstream mobile phones. This trial product is Tuhao gold.

2、 Appearance:

There is an old saying that Bubi doesn't know. Put my bracelet together with the Lexin smart bracelet Ziva, and you will understand why I like the Lexin smart bracelet Ziva at a glance.

The buckle of the smart bracelet Ziva also uses the metal buckle in the same color as the body metal. After special treatment, the surface not only has a wear-resistant appearance, but also has a frosty feeling. It is flat with the surface of the wrist strap to avoid friction with the notebook when using it. The watch buckle and wrist strap are connected by a single buckle. The wrist strap has 10 holes, which can be worn by different people. Each hole is embedded with a plastic protective ring with steps, which can be better connected with the watch buckle. It is unknown whether the built-in protective ring will fall off after a long time. Although the watch buckle is connected by a single button, its flat and long shape can prevent the wrist strap from shifting when connected.

The back of the bracelet is a heart rate sensor, which adopts the photoelectric heart rate detection method. Its principle is to use light to illuminate the artery, then reflect back, and calculate the heart rate of the human body according to the changes of the reflected light. Because of many factors such as the physiological structure of the human body, the color of muscles and blood, green light is the color with the highest passing rate in the human body, so the light source of the heart rate sensor uses green light to minimize the loss and interference. The Lexin intelligent bracelet Ziva can continuously monitor the heart rate. It is undoubtedly a good monitoring tool for patients with heart or related diseases.

Talking about the detachable wrist strap, it reminds me of a meter bracelet I used before. Because the main body of the wrist strap fell off, I lost two bracelets. The detachable wrist strap used by the Lexin smart bracelet Ziva is connected by a snap lock. You only need to press the lock catch to remove the wrist strap. This way of matching the wrist strap with the main body of the bracelet can completely avoid the problem of the host falling off.

It can be seen that the charging interface is located at the USB mark on both sides of the Ziva main body of the Lexin smart bracelet. When charging the Lexin smart bracelet, just remove the wrist strap corresponding to the USB mark. This direct charging design no longer requires charging cable or adapter, especially when going out, it is not only convenient to charge at any time, but also safer.

3、 Use experience:

The biggest highlight of the appearance of the Ziva smart bracelet is the breakthrough in size. The widest part of the ziva bracelet is only 17 mm, and the thickness is also controlled at 10.8 mm. The size is small, which is more suitable for beautiful women. I wanted to find a beautiful woman to be on the camera, but I have been out of town all the time. You can see the effect of wearing this local luxury gold bracelet. I don't need to say anything more.

The Ziva smart bracelet has two screen display modes, horizontal and vertical, and can customize the screen display. The effect of horizontal and vertical screen display is as follows:

In addition to the different directions of text display, there are some differences between horizontal and vertical screens. For example, the number of steps displayed in horizontal screen is in steps, while the number of steps displayed in vertical screen is in thousands of steps, which can only display two digits. This can be set in the mobile APP according to your hobbies or habits.

The heart rate detection function of Ziva smart bracelet can detect heart rate 24 hours in real time. It has been compared with a bracelet I used before. In the static state, it is found that the data measured by the two bracelets are basically similar, and the data detected many times are the same. During the activity, the detected data changes greatly, with a maximum difference of 20 times. This may be due to the difference between the real-time detected data and the single detection data or the algorithm, and the data is also for reference only.

In the actual use of the message reminding function of the Lexin smart bracelet Ziva, the accuracy rate of SMS reminding is much higher than that of WeChat. When using, WeChat information will not be displayed. When Ziva displays messages, it can automatically display the message content, which is commendable, but it is a pity that QQ and other information are not supported.

In daily use, the bracelet is inevitably in contact with water. The waterproof grade of Ziva smart bracelet is IP67, which can be soaked in water for a short time and can be used safely. The waterproof test used a tap to directly wash the bracelet for more than 1 minute, during which the operation screen was normal, and it was unnecessary to remove the bracelet for daily hand washing or bathing.

The main function of the bracelet is to count steps, monitor sleep, etc., and different bracelets often appear in the actual use process, and the data will have different phenomena. In this test, two bracelets are worn on the left hand at the same time. The following figure shows the data comparison obtained by wearing two bracelets at the same time. The number of steps of Ziva smart bracelet on that day was 8757, while the number of steps of the other bracelet was 9650, a difference of nearly a thousand steps. From the chart, there is only one record of the Lexin smart bracelet Ziva after 0:00, while the other bracelet has records every hour. This period is the sleep time, that is, there may be slight tumbling. Ziva, the smart bracelet of Lexin, has not recorded it, so it can be seen that the algorithm for counting steps is more accurate than the other bracelet. For the comparison of distance, the Ziva smart bracelet is 6.68 km, while the other bracelet is 5.5 km, which is just the opposite of the comparison of steps. In terms of the accuracy of distance data, let's first make a calculation. The average number of meters per step of the Lexin smart bracelet Ziva is 6680 ÷ 8757=0.76, while the other bracelet is 5500 ÷ 9650=0.57. For me, when I walk normally, each step is closer to the data of the Lexin smart bracelet Ziva, but when I walk fast, I prefer the data of another bracelet. In this way, for distance, the data is only for reference, and it is impossible to determine which model is more accurate.

As the second major function of the smart bracelet, sleep monitoring, Ziva is an automatic sleep monitoring bracelet, and the other bracelet needs to input the sleep monitoring time. For this reason, we used the sleep data of two days to compare and found that yesterday's data, because the sleep monitoring time set by the other bracelet is 7 o'clock, if this hour is added, the data of the two are basically the same. As for the comparison data of the day before yesterday, the total sleep time difference is as high as 1 hour. From the perspective of graphic comparison, it should be the difference in sleep start time detection. The truth is that during that time, although I had already gone to bed, I did not fall asleep. It can be seen that the information detected by Ziva is not more accurate than that of another bracelet. It is hoped that the Lexin smart bracelet Ziva will upgrade the data in the later stage and make more scientific analysis and accurate monitoring.

4、 Mobile APP:

Lexin Sports is a mobile APP software for Lexin system products, which can add and manage different health products under Lexin. The main interface of the software consists of home page, group, discovery and my four interfaces. The home page mainly displays relevant data. Groups and discoveries provide Lexin with richer and more interesting play methods for users. My goal is to add new devices or set the current devices.

In addition to the daily routine data, Lexin Sports also has statistical charts for daily, weekly and monthly data processing of bracelets, which is convenient for viewing the recent situation. The data of other products under it are independent, and there is no mutual connection or further judgment or processing of relevant data. It is suggested that the final analysis can be carried out for the data of different products in the later stage.

The Lexin smart bracelet Ziva can automatically monitor movement, which is also a new breakthrough. Conventional bracelets need to be opened manually, while Ziva bracelets adopt the automatic monitoring function, and after recent use, the detection accuracy is still very high. Now the latest system can also synchronize with the mobile GPS for more accurate movement data.

In addition to the appearance, the highlight of the Lexin smart bracelet Ziva is continuous heart rate monitoring. You can view the heart rate trend chart in the mobile phone APP. It is suggested here to have some health instructions or relevant health knowledge and precautions for heart rate trend. If heart rate monitoring is not required, it can be turned off at any time in the settings of the bracelet. Here, there are more function settings, such as alarm clock, long sitting reminder, call and message reminder, which can be set as required.

Summary:

In the actual use process of the Le Xin smart bracelet Ziva, in addition to checking the steps, sleep and other data, it is more used to raise your hand to see the current time. The Lexin smart bracelet Ziva can choose the right and left hand wearing mode, and the success rate of raising the hand to light the screen in different test scenarios for ziva bracelet is 100%. Of course, there are also some shortcomings in the use process, which are summarized as follows:

advantage:

1. High appearance;

2. Step counting algorithm is more scientific and accurate;

3. It can automatically detect operation and sleep without manual setting;

4. The protection level is up to IP67, which can completely cope with daily use;

5. Direct charging interface, convenient for charging anywhere at any time.

Disadvantages:

1. Heart rate monitoring can not be customized;

2. The sleep detection function may be inaccurate. It is recommended to optimize the analysis and algorithm based on heart rate and other data, and add functions such as dreaming;

3. Message reminder does not support QQ;

4. The content of APP is not rich enough, and it is recommended to add comprehensive data analysis and judgment results.

Although there are some shortcomings in the Lexin smart bracelet Ziva, it can be completely ignored under its high appearance aura, and some functions can be improved in the later system upgrade. Especially for women who love beauty, this bracelet is an excellent choice in terms of appearance and color matching. Finally, I would like to thank again Aigo for its trial use and manufacturer, and hope to provide more and more practical products in the future.
