This smart watch is very good in its stylist but there are a problem in this watch. The Bluetooth function doesn’t work properly. I bought a Raptas A1 smart watch before one month ago. This smart watch worked properly at least first seven days. But after seven days its Bluetooth connectivity didn’t work properly and also thouchable screen function. When I touch a item but automatically select another item in its display. Though it worked atleast first seven days it’s enough for me.
