My mother-in-law bought this Blue Hat Toy Company mp3 player for my two year old. I had never heard of Blue Hat Toy Company but I did some research and read reviews and I'm glad I did. But I also read a lot of reviews of people who didn't figure this out so here's your warning:... After fiddling with this for a long time, I realized that you have to turn it on (at the back) and THEN press the green play button to get it to actually power up. I kept thinking the batteries were dead or something when it didn't come on when I turned it on. It's a stupid design flaw, and I hope they fix it if they make a new version. But once you get past that, it works pretty well. It's durable and my kid has thrown it across the room and it still works. The batteries seem to last for a long time. I like that you can load your own music using a USB cable. I took off the silly songs that came on it and loaded on ones that my son likes.
