My review is based only on the functions I use, which are the clock, the pedometer and the sleep time,. I also use Bluetooth for syncing the data with the mobile App. I will start with the App, which is very easy to download and setup. You only have to enter your information in one place and setup Bluetooth connection in another’s.. Once you sync the data will populate the other screens. As for the data I noticed that the number of steps reported is highly unusual and is inaccurate. As for sleep time the watch is preset to track sleep from 10pm to 8am and you can’t do anything about it. The data collected for deep and light sleep is inaccurate too. It seems like the numbers for both types of sleep are similar every night no matter what type of night sleep you had that night. One last thing, I changed the face of the clock to show the time and date. I love the digital time display but the date is weird because it shows what day it is , Mon-Sun, and the month number, but no day number,
Cheap watch, DO NOT BUY. Dont waste your money or points. Very disappointed in this purchase. Poor advertising on this product.
