2016 is destined to be a year of rapid development of wearing smart devices. Smart bracelets, smart watches and VR devices have sprung up like mushrooms. Speaking of smart bracelets, the author has been in touch with them earlier. I remember that in early 2014, I used a body memory T9 smart bracelet. So far, the author has successively used body memory T9, Evi I5 IMO+、 The i7, InWatchT and other smart bracelets bring you a heart rate monitoring touch bracelet - Weile Now2.

The WeLoop Now2 is basically the same as the Now Classic in appearance. The screen adopts touch keyless design. It has the characteristics of call+message push, call firewall, automatic all-day heart rate monitoring, sports data sleep quality record, 3ATM (30 meters) level waterproof, and 2-week long endurance. The price of Weile Now2 is 199 yuan. At present, Tmall is pre selling, and the price is only 179 yuan.

The packing box of Weloop Now2 is relatively small, and the exterior is packed with transparent plastic cover. The appearance of Weloop Now2 can be seen visually through the outer package. The trial was provided free of charge by Lei Feng, so the packaging box was labeled with Lei Feng's trial logo. Lei Feng's trial has gradually developed from focusing on the evaluation and reporting of digital technology products to the first community of computer trendsetters. Focusing on digital technology products, it connects users with products and provides users and manufacturers with multiple system services covering media information, social communication, product trial and marketing. Welcome to pay more attention.

The side of the box shows Weloop Now2 from different angles, so that users can have a comprehensive understanding of the appearance of Now2 without opening the box.

The back is a brief introduction of its characteristics. Users can have an intuitive understanding of Now2.

The screen surface of Now2 is pasted with a protective film, which also prints the display style. On the premise that the screen will not be scratched during transportation, users can understand the display effect of Now2 earlier.

There is also a relatively small MicroUSB charging cable and a contact charging base inside the box.

It can be seen that in addition to the MicroUSB port with charging cable, the charging base of Weloop Now2 also has a reset hole. It seems that Weloop Now2 can be hard reset through this hole.

The number of contacts of the charging base of Weloop Now2 is 3. It can be analyzed that in addition to the two contacts of the power supply, the other one is used for resetting. The snap on the charging base corresponds to the groove on the Weloop Now2, and is fixed and connected by snap.

Since Weloop Now2 currently has no power off option, it will run out of power after being placed for a long time. The Weloop Now2 needs to be charged when it is used for the first time. According to the test, the charging current of Weloop Now2 is about 70mA, and it only takes less than 2 hours to fully charge. Now2 has a built-in 110mAh lithium polymer battery, which can guarantee the life of Now2 for up to two weeks.

The charging base is combined with Weloop Now2.

Now2 uses a 0.91-inch OLED screen with a resolution of 128 * 32. Touch screen keyless operation mode is adopted. The outer screen is made of high hardness mineral glass, which is scratch resistant and shatter resistant. You can wake up the screen by pressing the screen for 2 seconds or turning your wrist.

After the firmware of Now2 is upgraded, the display font will be changed from fine font to thick font to make Now2 display clearer.

Firmware updates of Now2 are downloaded directly via Bluetooth.

The convex part of Now2's back is a photoelectric heart rate detection sensor, which is a common photoelectric detection method in the market. At the same time, there are contacts on the back to connect with the charging base.

The photoelectric heart rate detection sensor emits green light to the skin to detect the change of reflected green light, thereby depicting the characteristics of heart rate change. It emits ordinary green light, which is harmless to human body.

Now2's photoelectric heart rate detection sensor adopts a prominent design, which makes the detection structure better contact with the skin and the detection results more accurate. The design of the heart rate detection part of Now2 is similar to that of Evi7, and the heart rate test results of the two models are basically the same.

The Now2 bracelet wrist strap is made of imported TPU material from Bayer, Germany. It feels soft and hard. The inner arc of the wrist strap is 200mm in circumference, and the number of holes is 10. When wearing, it is fixed with a single buckle. Users with a wrist circumference of 12-20cm can wear it comfortably. All wrist sizes of men and women are universal. At the same time, Now2 can use the Now Classic wrist strap, which increases versatility.

The contact surface of the Now2 bracelet wrist strap adopts a groove design, which is not the flat design of an ordinary bracelet. This makes a large gap between the wrist strap and the wrist contact surface, reduces sweat accumulation, and increases the permeability and comfort of wrist wear 。

In order to introduce the operation of Now2 more clearly, the author has made an operation video as follows:

The main interface of Weloop Now2 displays time, date and other data

Slide up to access the items such as heart rate, message push, and motion counting in turn

Now2 can only store three pieces of information at present

In addition to automatically monitoring the heart rate every hour, Weloop Now2 can also manually measure the heart rate at any time.

After a short detection time, you can see the heart rate data.

Summary:

The Weloop Now2 bracelet is the smallest size and the longest endurance of the heart rate bracelets I use. From the experience of the author until now, I have only charged the battery once. Personally, I am very satisfied with the endurance of Now2. Now2 is designed to be light and lightweight, weighing only 16g. At the same time, Now2 bracelet has 3ATM waterproof level, so you can safely wear it to wash your hands, bathe and swim. You don't need to worry about whether the bracelet will be damaged when you wear a wash. During this trial, the author would like to praise the attitude of Weile manufacturers. During the whole trial process, the staff of the manufacturer has kept in touch with the evaluation personnel in the group, always solving problems for everyone, and collecting suggestions from different aspects. Here I see the earnest attitude of the manufacturer of Weile. Is the intelligent device made in this way still poor~

The only thing the author is dissatisfied with is the display effect of Now2. The display effect of the screen is poor in outdoor sunlight, which is also a common problem of this kind of OLED display. If you can use a MemoryLCD display like Xiaohei 2, it will be perfect.
