Bought for my grandkids, they haven't gotten a chance to use them much but the ones that did seemed to like it. I'm not sure how long the charge will last, but a nice alternative to staring at a screen.

The company stands behind their product. The wrong size was sent the first time. they corrected the problem and we received the correct size right away.

It always needs to be connected to power source to use not mobile. the board is harder to clean than what is shown in your video I am disappointed as i bought 3 for grandkids and they are just sitting in boxes
