Today I received this smartwatch from Shenzhen Carol Import And Export Co., Ltd. Firstly I charged it, then I tested how many hours does it take to be fully charged, it spent around 2 hours.

The brightness of the display is neat, I just set it as 50% brightness, I went outsite on a shinny place, I was checking how good I can see the display ona sunny day, and I could see it quite well.

About the functions:
1. I tested cardio functions, I used both functions：there's like continuous bpm counter that is constantly checking your blood preasure. I also checked heart frequency's test, and it worked well too.

2. Messages, this app notifications really let you pick FB, Whatsapp, Linkedin, SMS, and so on.

3. About the step counter, I just walked 20 meters, and it shows on the smartwatch.

I think this watch quality/price is good. I mean, it's not like an Apple Watch, but it works well, the display is really big and it brights well, so it's good enough for me.

So I just recived the package, I fully charged one of the bands, then I just switched it on. I check every function is ok, just normal functions such as heart frequency and steps. Everything worked well.
