In fact, I was resistant to things I wore on my wristband, such as watches and bracelets. Mainly because the arm is too thin, it feels good to wear it. But sometimes it's inconvenient to look at the time. Friends recommend now2, holding a try to mind the order.

List of functions
The main accessory is the charging line
The bracelet body does not have a physical key 
You don't need to remove the handle ring when charging, you can charge it directly. It takes about two hours to charge the battery, but the standby is really powerful and can be used for more than 10 days. 
It's nice to wear it. Oh, my fine arm can hold it.
Turning the wrist or long press can make the screen bright and convenient. Swipe left and right to display heartbeats, steps, weather, and SMS messages. However, in the information screen state, the feeling is the entire screen, but it is not. The real screen is only the middle one.
My favorite function is waterproof. I don't normally wash it, but I still have to take a hot shower. There is no pressure to flush directly with water.
The details are very hard, especially if the design of this wristband is easy to sweat in summer. I heard that the material of the wristband is still of food grade. Anyway, wearing it for a long time did not find any uncomfortable skin.

But my favorite is the bracelet alarm clock. I usually feel tired and restless for a while. I'm afraid to overslept. Now I'm not afraid anymore. I'll wake you up on time and I have to say that the shock is quite strong.
Advantages: cost-effective, do not buy; functional, since I put it I basically did not miss the phone and text messages, especially if you have a girlfriend, if you missed the phone; standby time is long, full of electricity can be used More than ten days; waterproof, can basically wear all the time; wristband detail design is very intimate; as Yan value Well, anyway, the landlord likes it, I do not know how to see what the officials intended.
Disadvantages: As for the largest slot point is the poor visibility during the day and outdoors, especially in the previous version, later updated a highlight mode, but the feeling is still a bit unsatisfactory, but also under the premise of sacrificing standby Some features are still to be improved, such as sedentary reminders, music switching; there is a bright wrist screen, can only be in the case of waiting, does not support the flip wrist bright screen, very inconvenient.
But throwing away the shortcomings, for a bracelet is fully functional, but for the 199 price, it is still very satisfied, and interested friends can try it.
