Review on Waterproof Smart Watch for Android/Samsung/iPhone - Activity Fitness Tracker with Full-Touch Color Screen (Black) - Men, Women & Kids - Heart Rate & Sleep Monitor included by Timothy Spinner

Well first of all it's a smartwatch but more of a fitness tracker. We ordered two and found that one of these ran out of power very quickly and didn't communicate well with the phone even at close range. I contacted the seller and sent a replacement. The exchange worked much better. From time to time we have connection problems. We need to go into the app and unpair/pair the watch. The battery is pretty good. I keep mine completely blacked out and the batteries usually last about a week. Blood pressure is pretty accurate. I used a small sphygmomanometer, after checking it after hours, it was pretty much the same. The pedometer is pretty accurate. I was running on a treadmill and the clock was a tenth of a mile behind me. It is not that much. It took a few days to get used to, especially when sleeping. Now I hardly notice it's there. I had the original Garmin Vivofit and it does everything and more than it for half the price. Overall we are very happy with our purchase for the price.
