The sound is pretty good, the keys are solid and almost feel like a real piano's keys, there are lots of options and settings, a rec\play feature, headset support, and the power supply supports not only US, but also European voltage, which means international buyers won't have the problems of looking for a suitable power adaptor

The keys are just perfect for his little fingers

The keys are small (good for younger children), and it is obviously not a full keyboard, and there are no pedals, but it is a great keyboard nevertheless

I myself use this keyboard at a professional level at age 33 because I prefer mini-keys over full sized keys

The mini keys make this keyboard easier to play for some keyboard players.2

It has smaller keys than on my piano but that works well for a 7 year old

The smaller keys make it easier for them to play
