Nuband

This will b my second nuband..
Im disappointed...
First off according to my nuband i havnt slept for 72 hours.?! What SLEEP data was tracked DISAPPEARED

Secondly my data is lost from day to day?
For 80 bux not to mention cost of having iphone for nuband to work...
Id save my money and spring for a fuelband..
