Hello guys recently I purchased this Zakk U8 smart watch @ Rs.699/- from on line shopping, Its comes with G sensor, sleep monBrianbalakumaranr, pedometer, 1044 inch led display, mp3, mp4, camera, compatible with all latest android mobiles, Company advertised its stand by up to 160hrs buts its good joke, the battery back up very bad its drained fast, also I faced heating problem in watch at the time of charging, also touch is very hard to use, the camera quality like VGA or less than that very disappointed, the sleep monBrianbalakumaranr docent show proper record its not useful, also could not connect immediately to phone, suffered from disconnections lots of time I think its just like a digital watch. Dont go for this product.
