At least there's been decent customer service from the few people I've reached out to. It would be a lot nicer to have someone to talk to on the phone to get answers to problems in minutes instead of the back and forth email communication that takes hours or days... Bottom line, I expect more than two days of functionality from a device after paying $200. I've had to send back broken Biostrap wrist devices twice already, and the third one I currently have doesn't work. Guess I'll have to wait during another week or more in limbo while shipping back my current broken device and hoping to receive a 4th device in the mail that actually works.... beyond frustrating.
