The band is super soft and very comfortable. The watch is light enough that she doesn't feel uncomfortable wearing it to bed. She wanted a watch that was comfortable to wear to bed so she could track her sleep activity and cycles. It comes with a nice instruction manual and a magnetically attachable charging USB cable.

The fit and finish (metal band) is very good, and also comes with a de-pinning tool to adjust the band. The display is bright and sharp, and the watch has more features than I'll ever use! I bought it because it is beautiful, and has excellent features (the cardio stuff interested me), plus the display is easily changeable. A very good-looking watch for the money! I'm very pleased with the quality!

Very nice watch that I bought for my goddaughter. It works very well, she is delighted to receive messages on the watch. It is easy to use and for its price it is a little gem!
