I have this set up in my home office (10x10ft) and I'm telling you this sounds like a real piano. I've been learning on a small, cheap electronic keyboard and this has been the biggest upgrade to my experience. I look forward to practicing every day now. There are also around 125 other sounds to simulate. The speakers are seriously good quality. I did notice it feels a tiny bit off-center when you pull the keys out, but if you attach to the wall you should be good. If you jumped on it I'm sure it would fall over but while playing it doesn't move at all and still feels solid. It also just looks good sitting when the keys are pushed in. It only took 6 screws to assemble. There are a lot of other electronic features and sounds, and you can even record yourself playing and play back. If you need to record via a computer or use it as a MIDI controller you can too. This thing has it all, I'm over the moon with this thing.
