DO NOT PURCHASE FROM HERE!!! Brought two kids fitness trackers for my niece and nephew for Christmas, both of which are faulty. One of the watches does not even charge Setting the watch up was painful due to terrible instructions, written in minute text which is barely readable without a magnifying glass. app). The heart/bpm monitor feature did not work and showed 0 bpm whether sitting down or running around. Battery life is approx 2 days, even when left lying around. The watch randomly and frequently buzzes for no apparent reason. The step counter is BEYOND inaccurate. One afternoon, the watch clocked up 500 steps whilst sitting on the sofa watching a film. I have since returned the watches for a full refund by special delivery to the given address, we have evidence of this being signed for, and now no refund and no response to emails. CON ARTIST DO NOT BUY!!
