I've never played the keyboard before, but always had a passion for it. In short I love this thing. It's really well built and good quality. Just in case you were a beginner like me and you had no clue about keyboards then I'll tell you it's powered by an AC plug. You can enable and disable touch sensitivity on the keys. It has a little screen with a piano on it, so everytime you play a key it shows up on the little screen and also shows you which music note you are playing. It has built in songs. When you play the song each note played shows up on the little screen, so you can learn how to play the song. Unfortunately I was upset to know that a MIDI output USB cable is not included, but you can buy a decent one for about 5-10 pounds. Aside from that P&P were really good and I'm really happy to have bought it :D
