Feels like a real grand piano! In great condition. Was recently cleaned internally, and checked by a Roland repair specialist.

"With 88 pro-quality, fully weighted keys, the A-88 sets a new standard for streamlined, portable MIDI controllers. Its Ivory Feel-G weighted keyboard -- a trusted asset found on high-end Roland workstations and digital pianos -- brings a new level of grand piano luxury to the portable MIDI controller market. But even with its premium keyboard, the A-88 remains slim, compact, and easy to transport. For players looking for great weighted-keyboard action in a portable package, the A-88 is the best MIDI controller available."
