Review on FITVII Smart Watch: Heart Rate Monitor, Waterproof Smartwatch with Sleep & Blood Oxygen Tracker - Perfect for Women and Men by Edwin Kreps

I like its smoothness, the rose gold/pink color is very similar to the iPhone 3 watch; It performs all the functions as described, it even warned me when I was sleeping when the watch pressure and oxygen levels were too low. Setting up and using the phone is very convenient. The app has a slight learning curve, but other than that it works great. I associate the phone well with eye health, as well as my friend in fitness and Google Fit it seems. The synchronization is quite simple and works quite well. The precision is almost close; This is not a medical device so I don't expect it to be 90% accurate or better. Not exactly sure about the battery life but it seems to last, but I don't use an oxygen monitor or continuous heart rate or continuous sleep while awake. The update was quite easy and quick. Would I buy a watch again, yes! I have a suggestion: to be able to view the messages that came through my watch so the icon is easier to find.
