To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
We got this as a Christmas gift for a 5 year old. I LOVE IT! It's easy enough to use that he can do it on his own. So far, we haven't run out of space with two dozen songs and some podcasts. It will hold "pictures" but they are grainy like from a really old cell phone. But - I didn't buy it for that. The sound is good quality. I like that it's not ridiculously loud. If you want it louder - attach a speaker OR headphones. I haven't timed the battery life - but it goes for hours. Still running strong 4 months later. I haven't put any of the MP3's on (my husband does that) - but he seemed to figure it out easily and quickly.
My son uses this on the bus. He needed a distraction and we put all of his favorite songs on it. He also uses it before bed to listen to songs and fall asleep. I love that this MP3 player has helped him to love music.
