As so far trusting the brand decided to try this smartwatch after a standard one from Samsung. Experience so far that easy to adjust and get used to the menu, connectivity with mobile phone (not Oukitel) looks seamless and stable. Health measurement looks accurate. I am not sure about the strap though, looks cheap and unsafe, but using only for a week, so no real field experience so far. First time charging a little bit strange, there is no indication on the percentage during charging, tried several ways, only got a standard charging message. Also, the watch is very heavy, but that was expected.
