Bad

Disappointed. Old version was great and just worked. Now my cuff is a worthless piece of junk. Dont buy from them. My other devices (Oxygen, weight, etc,) have displays so you can at least use them when there is issues with Bluetooth, the qardio cuff has a single green light that doesnt tell you much and now with the app update it isnt working at all. Stay away.
