Review on 💓 Mio Slice Large Sienna Heart-Rate Monitor by Jessica Shakman

I am very disappointed. This is a nice, stylish tracker, but it has too many flaws. It often loses connection and you have to go into the app itself and force stop the app. You must then return to the main application to verify that it is connected. Often this is not the case. You should not connect it for call or SMS notifications. The battery life is terrible, it only lasts a day, after that it has to be charged. Most people charge during the night, which is contraindicated if you want to track the quality of your sleep. I emailed the company with my concerns and didn't go too far. Let's hope that the firmware will be updated at some point and this will solve the battery drain issues. I hope they spend more time and research on this activity tracker. I don't like leaving negative reviews but I don't want people to waste their money and be disappointed.
