It arrived yesterday, I'm using it and it seems to be very good, the compass and GPS functions work well, compatible with Strava, I haven't tested it in the water yet.
I've been using it for two days and it seems like a very good watch; the calls sound great, and the flashlight is excellent. I haven't been able to test the battery yet, but it seems like it will last quite a while.
Quality for the price, excellent.

The GPS works well, but it's a shame that there are only 5 sports modes with GPS and no swimming mode, so no distance calculation is done while swimming.
I do not recommend it for use in swimming pools or open water, no point.
I liked the watch. The GPS connects quickly, unlike the Aura Fit, which I had to beg to make it work. I already know that I can't get the watch wet. Even though it says it can be submerged up to 10m, my experience tells me not to take the risk. It accurately measures running and walking distances with a well-tuned setting. I just wish the body was metal, but it's plastic.
