Received my 2 Bytetags and went to the app to set up an account. The password input doesn't allow you to check what you've typed in for your password. As a result, if you hit a wrong key you don't know it and your password is good for nothing. Most sites give you a way to reset it. They don't. There is NO PHONE NUMBER associated with this company. NONE. ZIP. NADA I discovered their BBB rating is F and they are a scam, never respond to emails. DON'T PURCHASE FROM HERE!
