I bought this piano mat for my nephew and I have to say it is the best toy to give as a gift. It's huge, with good sound quality and 10 different instruments. Also, it seems safe since we don't need to plug in wall chargers/adapters. Recording and playback is a very good feature. My nephew just won't stop dancing and playing with it. The seller's (greatdealsonus) service was satisfactory and timely.
