From the first impression, the watch is great, looks excellent on the wrist, everything works; in short, the watch is at the testing stage. The strap can be detached very easily for replacement.

Appearance, quality of workmanship, battery life lasts 10 - 13 days - this is good. About bad - not every day do they recognize that I'm sleeping)) no sleep data. Heart rate on training programs is not always displayed correctly throughout the workout.
I used it for weekend hiking, and the metal case is sturdy and the screen is visible even in sunlight. The GPS is accurate and the battery lasts long.
The product and its contents match the description. The bracelet is slightly lighter than the watch. It fits comfortably on the wrist. Connects quickly with the phone. Haven't tested all the functions yet, but they seem quite fast. Quite brutal and worthy men's watch.

In the end, I settled on this T4 model, and I couldn't have made a better choice! He says that the watch is incredibly comfortable to wear, and the battery lasts almost a week. He especially likes its durability because he knows it won't get damaged if hit. The delivery was fast, and the packaging was excellent.
