First, my order took 8 days to arrive, even though it stated 3-5 days delivery. So it turned up a day too late for a birthday gift. When I emailed for an update I was told that they're small warehouse try there best to despatch products quickly. The return postal address was a house, a very small warehouse indeed. There was no invoice or receipt enclosed either. Second, the app to connect the watch was not working at all. Tons of reviews all complaining about it. Product was returned and a full refund given.
