benefits are listed in the description of the watch
inability to set the automatic brightness, if I set the brightness to make the dial readable in the light, it is too bright in the dark
you can't uninstall existing apps and install new ones
no sounds can be changed (ringtone, alarm, notification)
the meaning of some icons is unclear (they have no description)
the creation of a custom dial is limited to the choice of background and whether the time (in a given font) is displayed in the upper or lower half
inaccurate sleep measurement
inaccurate measurement of steps, I can't judge the accuracy of the sports measurement

Wonderful design
Large display
Menu and apps in English
Good battery life
Measuring during sports is almost useless. Distances, number of steps, heart rate measurement have huge gaps so then there is a meaningless averaged value of the result.
Pairing with a cell phone is so half and half. Contacts have to be transferred to the app, the watch can't do any of the navigation on my phone, phone calls work but it's awfully quiet
For me, the lack of navigation, either by pairing or offline maps, along with inaccurate measurements and frequent outages make it unusable
Better to overpay and buy a more expensive model of a reputable brand.

What bothers me about the watch is that even with the GPS turned on, in the RUN and WALK mode, the distance covered is not derived from GPS, but from hand vibration. When I walk with hiking poles, it only shows about 1/3 of the real distance. When the traveled route is then exported to the application, the recorded route is real, but the distance is still only one third. It would probably require a fw fix. So when I walk, I use the Cycling mode, where the distance is absolutely accurate, but the other calculations around are wrong again.
