I just received my watch, I am thrilled to use it! Sleep tracking works, charges fast, easy to use. I went with black on black because I'm not a fan of silver, and I love the look/color. The watch face I selected is bright enough, but not overwhelming. Definitely seems like a great value for the money, but time will tell.
Update: 12/10/24- so I've had this watch for one month now and I absolutely love it. The only thing I would say that is negative about it, is it needs charged a lot... But other than that I am so happy with my purchase.
