Everything is fine with this watch but you can't change the background except for the preset ones.. It throws you out of the app and nothing changes.

It is worth writing a review because it is worth the money and more. Very beautiful watch, very nice colors on its screen. It seems to have accurate measurement. And when you speak into its microphone during a call, it has a very clear sound, almost crystal clear I would say. Also, another advantage is that you can manually dial any number you want to call, apart from the contacts. Also, its battery lasts for many days, of course depending on the usage you make of it. Personally, I am very satisfied.
