Bought for my 10 year old son, I find it looks a bit big on his wrist but he doesn't seem to mind. The watch works great, and he wears it daily. Was pretty simple to set up, the backlight is a good feature to. It does seem to be waterproof, he wears it in the shower or bath without issue. It has 2 daily alarm features which were easily set up, and the watch beeping tones can be turned off completely and all settings can be locked, so even if he plays with it in class it wont disturb anyone. (Until he figures out how to undo that, its been great as he is quite a constant fidgeter!) Very good quality and at 19.99$ its a great buy! Quite happy with my purchase and am considering getting another one for my husband.
