Review on 🏋️ DoSmarter Fitness Watch: 1.3" Touchscreen Smart Watch with Heart Rate and Blood Pressure Monitoring, Waterproof Tracker with Sleep Tracking, Pedometer, and Calorie Counter for Women and Men by Sara Reyes

I waited a few months to test this watch to make sure I was accurate. These are great watches. Every function works well. Calibrating your blood pressure readings to personal blood pressure readings is about as good as using a watch. Keep in mind that this is not a medical device, but it gives you a good idea. All other tracking data is correct. The app works fine. I've only had it turn off once. If you go out of Bluetooth range (which seems great - I can keep my phone in the kitchen and stay connected throughout the house) it will automatically reconnect every time you get back in range. It also doesn't seem to kill my phone's battery. In fact, I don't notice any difference while it's running in the background. The dials are really good. I wish there were more or could be upgraded, but the four that are there are good. The sleep function works well. Very good from what I've seen (I only wear it occasionally). The battery life is insane. You can easily get a week for free. Since I don't wear mine all the time when I sleep, I can go about 10 days without charging. And this with full monitoring and receiving alerts throughout the day. I originally had another watch (a different brand) and returned it when its "long life" battery died after a day or two. Important - Charge this watch for FOUR hours. Not two. Both are in the instructions. After 2 hours it shows that it is fully charged, but it is not. Four hours of charging is the maximum and gives you the lifespan I have described. The watch appears to be quite durable. I wear it every day and haven't gotten a scratch yet. I've worn it in the rain and it's ok. I don't submerge it in water so I can't comment on how waterproof it is. All in all, if you want a watch with a FULL round screen and great/accurate performance without spending a lot of money, this is the one for you. I highly recommend it.
