I purchased the band on the very first sale but it disappointed me as the sensors used in the band are of poor quality and not reliable in any form the sensor counts the footsteps even I shake hand with someone I never got accurate result from the band and returned it to the amazon thanks to their easy return policy you can go for othe bands which are far more accurate than the tu fit band the only important feature find in the tu fit band was the display that to a scratch magnet I suggest never buy this band
