The bracelet should be the fastest popularized wearable device. In recent years, both large manufacturers such as Huawei and Xiaomi, and many unknown small manufacturers in Huaqiangbei have tested the bracelet. At present, the bracelets on the market have gone through the initial stage of various functions, and have begun to take the path of subdivision and focus: for the direction of movement, information reminding, recording daily movement, medical and health care.

I really like the packaging style of the Evian i7. The white packaging gives people a delicate and fashionable feeling. Among the bracelets and watches I have used, the packaging is comfortable to look at. The back is a brief introduction. There is nothing more to say.

I got the Evian i7 in black. Compared with the exquisite white package, the black Evian i7 is much more low-key. Although it is not as exquisite as the Huawei Watch, it is good at the same price.

The i7 adopts a square design. There has always been a debate about whether the smart bracelet should be square or round. My personal opinion is that whether it is square or round, as long as it looks good. The i7 is a beautiful example of square design.

The front of the Evian i7 dial is made of 2.5D curved glass. The official said that the 2.5D glass is made of super strong reinforced glass. In the past two weeks, there was no scratch on the dial surface. The scratch resistance was really strong. There was no problem with daily use. The whole dial is made of all metal body. Later, it is treated by sanding process, which makes me feel full of metal texture in my hand and very delicate on my wrist.

The watchband is made of medical grade TPU material, which is very comfortable to wear.

The back of the dial is the interface between the heart rate sensor and the charging magnet. The Evian i7 has a built-in 100mAh polymer lithium ion battery. For the capacitive screen with a non color screen, 100mAh is still enough. My actual test generally lasts about 5 days without problems.

Finally, we introduce a wonderful little innovation of Evian i7. All the bracelets we have used have ignored the pros and cons when charging, which has led to the failure of charging all night. In order to prevent users from not knowing the positive and negative directions when charging, the i7 uses the magnet principle to distinguish the charging sequence. The reverse direction cannot be installed. This function seems to be a small function, but it actually solves users' big problems, which is worth praising.

The i7 app supports Android and iOS, two mainstream platforms, and can be installed by scanning the QR code on the box. The specific installation steps will not be repeated.

After entering the App, you can choose to register an account through QQ, WeChat or yourself. This kind of wearable device is an effective way to create a fitness social circle with your QQ and WeChat friends through social binding. This kind of wearable intelligent device's step recording function is a necessary function. My own experience in the past two days is that the step recording is very accurate. The error of 1000 steps is within 10 steps.

This article mainly introduces a more practical function than simple step recording. Select GPS track in the App, and there are three options: "cycling", "running", and "walking". Compared with simple step recording, this function can display speed, average speed, heat consumption, and even detailed speed curve in real time. Through these data, you can record every movement in detail, and have a detailed and in-depth interpretation of your physical strength, which is much more scientific than simple step number recording.

The i7 smart bracelet also has a message reminder function, which currently supports calls, SMS QQ、 WeChat message push. Compared with the wearable devices of friends who push many unimportant information such as Weibo on their mobile phones, Evi7 only selects the most important functions at present, so that the information push is targeted.

Sleep monitoring functions include sleep data analysis, main factors affecting sleep, and so on. Of course, as a bracelet, the advice given is certainly not as accurate as that given by professional doctors, but it can still serve as a reminder. It can't be said that it is useless

During this period of experience, Evian i7 has quite good experience in the essential functions of the current bracelet, such as movement recording, sleep monitoring, and information pushing. It is also comfortable to wear. The endurance can last about 5 days. I am still satisfied. The price of 299 yuan is very competitive.
