At last I got this watch. Being a 1st time user of a smart watch I am very excited. This watch can sync in with my android phone and all features working great. Tried it out with my friend's iphone 6s but some features missing.
I always wanted a smart watch but looking into the price range I kept my wrist away from such technology but this one made my wishes come true. Moreover I got it directly from china so it costed me way to less than what it is sold in the indian market.
I do not know about shipping time since this was bought physically from the country. The best part is it comes with all accesories like usb cable and earphones battery already includes and an user manual.
Sync it with your android phone. I would resist in syncing an iphone or just insert your sim card and memory card in it and use it like a phone.
