Reasons to purchase
Sports bracelet this thing, used six, previously bought 134 are bong2, 256th are bought millet bracelet 1.
Why? Because when bong2, that special-shaped battery power is not enough, ah, no use how long it will be no electricity. Can not charge, and then the battery is still out of stock, then add two to the whole family mobilization, his wife is not happy to wear, they are natural loss of batteries. Although millet bracelet 1 can be charged, but sleep monitoring is not allowed, ah, my old days of noon sleep, it is not considered sleep time. The most important thing is that when the millet wristband is on the 1st generation, the wristband of the bracelet is easy to be broken, and the wristband is also particularly easy to fall off from the wristband. My three millet bracelets are all gone home at night and it's gone. of. So although it is a standard rice noodles, but think about it later do not want to buy the fourth millet bracelet 1, and so on behalf of the 2nd generation, and grab the grab, slightly annoying.
So there was no hand ring for some time. Then this time, there were new products in bong. Jingdong started pre-sale registration and it looked like the function was good. This time it was finally charged. Buy buy buy.
Bong 4 smart bracelet sports bracelet heart rate monitoring vitality monitoring type running training calls to remind custom dial sleep monitoring Meng pet calorie develop black 199 yuan Jingdong direct link out of the box drying on May 9, on the next day at noon received. Aunt routine first open a box. 
This time it was replaced by a green box.
The inside of the packaging, the main body of the bracelet, the charging head, and the instructions.
The main body of the bracelet is a bit thick. About 1cm. But it doesn't really feel like wearing it.
Just 8% of the electricity was just out of the box, and the time and date shown were not accurate.
The bong was loaded from the millet official store. But I couldn't find the bracelet. I thought it was low battery, so I charged it. But wait until I am full of a look, or not. Then restart Bluetooth, restart the phone, and reinstall the APP at the millet official store. Not successful. Obviously, bong4 has been successfully paired in the Bluetooth of the mobile phone.
Toss for a long time, want to return, and asked Jingdong's customer service. The customer service asked you how much the APP version number was. It looked 2.3.2. Then customer service said that the latest version number is 2.6.1, to a official website to download the link. After installation, it was normal.
After the connection is made, an upgrade is required immediately.
The version of bong4's APP was quite different from what I used to use bong2. The function seems to increase a lot.
In the screen content, the contents of the screen display can be customized. 
Benefit from having a nice screen. In the screen settings, the dial graphic can be selected and the style is quite a bit more.
Like numbers or pointers have options.
Gesture control function, when lying on the bed, turning his wrist to see a good time. Compared to watching the phone, the screen is too dazzling. It's not easy to wear a watch when you sleep at night.
Automatic heart rate monitoring can form a heart rate trend throughout the day. This function is also available. It was the morning when I was riding my bike, I used a heart rate belt to compare the accuracy of the heart rate test. It is a pity that my heart rate has no power, no data feedback, and this time it is no comparison.
The event reminder is to make your body move when you sedentary.
The alarm function can be set for light sleep, and the strong sense of tremor in the morning is more impressive than the non-rechargeable motor of bong2. You can call the alarm clock instead of relying on the phone, and you are not afraid to wake your wife and baby. The lazy pattern is estimated to be repeated shaking every few minutes.
The news reminded me that I think that spam messages are also quite a lot of one day. QQ group and WeChat group are also very annoying. This will not open. Of course there are more than no.
Incoming call reminder, this function is a bit necessary, sometimes a meeting, the phone will be set mute and forget to open back.
There is nothing to talk about if you do not want to be disturbed. The night does not want to be disturbed by others.
Finding a bracelet is also a regular function.
The data report has four parts: activity report, sleep report, heart rate report, weight report.
Discovered a very interesting feature, in the timeline and data report this screenshot, will automatically remind you whether to share to friends, good friend of the sun design.
For the content of several reports, I think this is the strength of the company's strengths in data monitoring and statistics.
The first block of daily timelines. There are also three modules, exercise, sleep and weight.
There are four options for the sport mode. The choice on the app is the same as on the wristband.
Biking interface opened in APP. It takes more than 5 minutes to be recorded. I think this integrated bike record is not bad.
There is a running training in bong's sports. Can give you a running real-time reminder. Prevent excessive damage from running. I think this feature can be praised.
The third module of APP: Discover. Really surprised.
Amusement Park's first function: group, allows you to find the same like-minded sports people.
The second bong elf seems to be a pokemon fed with the calories you consume. Think of all the flesh on your body and feed it. There is no body to Buddha.
The third onlookers. Various forum posts, it seems that bong operates well.
The fourth, step-by-step. Send insurance with the number of steps. interesting.
As for those who like to climb the number of steps in a circle of friends, bong can also be combined with WeChat rankings and QQ sports.
I am personally satisfied with the upgrade from bong2 to bong4. The problem of at least power is a perfect solution. On sports statistics and other data, I think that the company bong has been doing more professional (as compared to the Mi family). There are timely feedbacks during the run. After the exercise, the advice given is also good.
Therefore, this time bong's ad words are good and the run points are useful. Not every day is a mess.
May not lose weight in May, after the Dragon Boat Festival is really summer in June, you sad to it?
