An interesting instrument - there are few digital pianos with 73 keys and with configuration of notes (usually 73 key pianos have 5 full octaves and a few keys with lower notes and a few with higher notes like Yamaha p-121), and it is the only one in this price range. Build quality is okay, the power button could be better. The speakers are OK in terms of volume, although the sample of the piano and other instruments is of average quality. The action of the keys is not perfect and not suited for more advanced fast pieces and the keys themselves also seem "cheap" to the touch, but its still much better than, for example, the more expensive Roland GO-Piano.
