Review on KATBUU Fitness Waterproof Smartwatch Stopwatch by Jill Bennett

I don't use it for training/exercise so I can't rate this feature. It only relates to my mobile phone to access features and information history. I use it to track sleep, monitor blood pressure, heart rate and steps. not 100% perfect but I'm very satisfied damn the cost is so low I won't expect perfection. I have read reviews from those paying hundreds for a well known brand and even they are not satisfied. If I'm inactive for too long, it reminds me to get up and move, and my blood pressure readings are accurate 50-60% of the time. Oxygen and pulse normal. because I don't use it for battery training the last 5-7 days before I need to charge it. I'm satisfied so far
