Ordered two for my kids "from Santa" for Christmas. one didn't turn on at all and the other turned on, but the batteries only lasted a few hours on a full charge, then after a proper charge they only lasted a few minutes and died again. It's hard to explain to kids why Santa gave them trash π’. What this watch is supposed to do would be great - many other brands don't offer the ability to play music/MP3 files. But if it doesn't charge/turn on, it's pretty much useless. Next time I will choose a more reputable brand, 0 out of 2 features are terrible.
