Four stars simply because it is a few nanoseconds slower in the UI than the Apple Watch. Other than that, flawless. It works with all Androids doing everything and is the only stylish Android smartwatch in a world of 45-47-49mm diameter frying pans and 15mm thickness. Another downside is the lack of accessories. Only from China and very limited.

I had read the mediocre reviews and had doubts. After using it for quite some time, I can say that it is excellent! Well done, Google!
The only observations are the battery (which, for me, with wifi, many notifications, and some calls, easily lasts a day) and the size, which may seem small in some hands (ideal for me).

I charge it once a day. It definitely brings improvement and Google should take it into account for future devices. Personally, I live with it. Otherwise, it's excellent. Nice design. Easily customizable. Comes with a 6-month free subscription to Fitbit premium with plenty of options.

And I put many things on it for 2 stars.
It's nice but it's not worth its money at all!!!
The battery is a joke!!!!
The value for such a watch is max 100 euros, it's not worth a single penny more

I didn't go crazy, especially in terms of software, the wear os is very mediocre.
Few functions, generally I expected more frequent updates but here basic things are missing.
The battery doesn't even last a day and the basic strap irritates the skin after hours.
It's okay but I wouldn't buy it again for any reason.
