Bought the total health bundle with high hopes and a lot of excitement, but was disappointed in almost every way. App did not reliably capture sleep, could not edit sleep times, are just a few of the issues with the Android app. Very responsive online customer service from Cyan, but should not need it in the first place. Then after about a week, the wrist sensor all of a sudden stopped working. Would not connect, etc. Tried everything in the FAQs and dialed up Cyan once again. Very responsive again, but clearly not given the appropriate guidelines from his/her leaders. I was told that my wrist sensor was "in a state of Brick" and that I would need to wait 3 days for the battery to drain fully, then try to charge and connect, and if that didn;t work, wait an additional day, and try again, then if that still didn't work, they would replace it BUT only after I had received and printed the USPS return label and the return package had been scanned by USPS. Then, and only then, would they send me a replacement and they could not overnight it. Clearly they don't have the product working right, they don't have their processes and customer service policies dialed in, and those are always the result of inexperienced leadership. Too bad, I was hoping this would be a great device that I could use personally and consider endorsing professionally. Had to cancel and request a refund for the whole bundle plus accessories. And even then they charged me 2x a $25 restocking fee... to take back the defective device! Zero stars if that was an option...
