I am far from expert level so I am used to and content with playing on cheap keyboards and out of tune pianos. To me, this portable, slim keyboard is luxury. The keys are far from cheap and the sound is authentic enough for me. 76 keys is just enough for fur Elise and there's 2 settings of electric piano, organ, strings, vibes, harpsi each. There's even a usb (to host) outlet on the back (wire not included).
