Review on 📱 chalvh Smart Watch: 1.69" Touch Screen Fitness Tracker with Heart Rate Monitor and Sleep Monitor - IP67 Waterproof Smartwatch for Android and iPhone by Darion Wooten

I bought this watch at the end of April and it worked perfectly until about July 15th. The problem isn't that the phone is transferring data or connected to my phone, the problem is that I can't turn the watch on by pressing the switch on the watch, so the only way to use it is with my phone. The only way to turn on the screen is to use the phone app. So I'm deducting two stars. The data seems to agree fairly well with my Omron blood pressure monitor, but the blood pressure on the watch is a few points lower than the monitor.
