No feedback on Hisense smart watch

Got the Hisense U1 smart watch 2 weeks back, haven't been able to you use as the application off Play store is completely useless, the watch stays connected for about 5min then disconnects. I have sent numerous emails to the developers no response, the reps at the stores didn't even know they had a smart watch. I will never recommend this product to anyone as there is 0 after service.. Guess you do get what you pay for, shame on you Hisense
