With the development of science and technology, the growth rate of intelligent devices is getting faster and faster. At present, there are endless smart bracelets on the market. In my opinion, a qualified smart bracelet needs to have the basic functions of time display, message display, sleep monitoring and step recording at the same time. This time, I am very lucky to have obtained the i7 smart bracelet from Lei Feng. Here's how to use it these days.

The package of the i7 is very simple. The silver "iwown" is printed on the pure white background. The hard carton can ensure the safety of the i7 even if there is a collision during the delivery process. The stickers on the back provide the QR code for downloading the app and the hardware requirements for use, as well as some basic information of Avery. After opening the package, you can see the i7 smart bracelet of the protagonist at a glance.

In addition to the i7, there is also a charging line, a long instruction manual and a business card of Evei personal number in the package. The instruction manual details the use method and basic functions of i7, but I think it is also necessary to add "long press confirmation" to "basic interaction".

Back to the bracelet itself, the i7 is relatively small (39 * 31 * 8.4mm) and adopts a full metal body design. The ultra-low power consumption Memory display screen not only guarantees the endurance, but also ensures the display effect in strong light. The i7 also adds backlight function, so that users can see clearly even in dark conditions. The glass on the surface adopts the popular 2.5D curved glass, and the transition between it and the middle frame is also very smooth, with a strong sense of integration.

There is a bulge on the back of the fuselage, which is its AMS heart rate sensor. During heart rate measurement, it will emit green light to the skin. When our heart contracts and expands, changes in the amount of blood flowing through the blood vessels will cause the expansion and contraction of blood vessels, thus modulating the light. Heart rate can be obtained through this modulated light. The three metal contacts below it are charging interfaces, and the charging line is magnetic adsorption type, which is convenient in actual use. This charging mode also greatly improves the integrity of the whole machine, making it IP65 waterproof.

The Ivy i7 uses a standard watch strap interface, which greatly increases the richness of our watch strap replacement. The original watchband uses TPU medical grade materials, and can adapt to a wider range of users through the nine card holes above. In the actual wearing process, the buckle is firm and comfortable, but the watchband is slightly stiff.

As a smart bracelet with a capacitive screen, the i7 can complete many operations and data display without using the App. For example, sliding on the home page can display the current steps and remaining steps, distance traveled and remaining distance, heart rate display, calories consumed and remaining calories, and right sliding can display sports mode, messages and functions. We can see 8 historical messages in the message, which greatly reduces the number of times to pick up the phone, and the actual experience effect is very good. In the function, the dial can be replaced. There are three built-in dial options. At the same time, it can also support black and white anti color, automatic heart rate, shutdown and other operations. It can be seen from these functions that the i7 has high availability and practicability even without the mobile phone and the App.

Although it is mentioned above that i7 is not as dependent on apps as similar products in the market, it also needs to combine apps to play a more complete function. The download of the app can directly scan the QR code in the manual. After opening it, you can see all the information of today on the home page. If you want to view the details or historical information, you can click in. It is quite reasonable in the operation logic.

In the "My" column, you can view or edit your own information. You can also authorize WeChat Sports and QQ Health here to share your sports information with friends more conveniently.

The big microphone button in the middle is the voice function built in by Evian Health Assistant, where you can directly use voice to query some information or set alarm clock and movement target. However, I don't think it has much effect. I haven't used it in this period of time, but it can be used as a function similar to "global search".

After clicking the current bracelet on the home page, you can set it in detail or upgrade its firmware. Except for the three settings of sitting reminder, message push and backlight, most other settings can be directly completed on the bracelet. Message push is a very practical function. i7 can support SMS, WeChat and QQ alerts, and can add software by itself. It can be said that such a function is one of the important criteria for me to choose a bracelet.

The backlight setting is to enable us to see the words on the display clearly in the dark environment, so it is better to set it according to the actual situation. In the time period you set, the backlight will automatically light up when you lift your wrist, and the recognition rate is good.

The Evian i7 uses a 100mAh polymer lithium battery. According to the official introduction, the endurance time is 7 days after the automatic heart rate is turned on, and 20 days after the automatic heart rate is turned off. The endurance performance is quite good. In my use of this period of time (the automatic heart rate is enabled), I found that the time is not much different from the official announcement. Maybe everyone's different use habits will lead to some deviations.

This product is an excellent work, complete functions, excellent endurance, and exquisite workmanship. When these are combined, the i7 is created. However, I think the vibration is too small during use. Although the strap material is comfortable, it is a bit hard. I hope it can be improved later. At the same time, it is hoped that more abundant dials can be added in the subsequent process for users to choose. Finally, thank Lei Feng.com for giving me this opportunity to experience.
