Review on Cycplus Waterproof Heart Rate Monitor Armband - Men and Women, Bluetooth/ANT+ Compatible by Stephanie Ingram

Very intermittent connection with phone and apps. I was able to connect it to some applications the first day I received it. It later connected and fiddled with other expensive applications. I had to turn it off and on multiple times to get the connection. It takes a lot of time and effort to connect to applications. On the second day, I can't connect to ANY applications. The battery is fully charged. ***UPDATE BELOW*** After initial crashes it works much more stable after restarting my phone. I have raised my rating to 4 stars. I'll keep updating it as needed, but as it worked flawlessly two days in a row I'm giving it 4 stars for now, hoping that the initial glitches were due to my phone's recent update.
