Nice graded weighted feel on the keyboard. Quite firm action on the keys. Solid metal construction. The backplate where you plug in the wall wart power cord and usb/MIDI connectors is a little cheapish. Comes with a cheapo foot pedal, but you can buy a good one and it is fully compatible. I use it as a master controller for a home recording setup. It seems like that's what it was designed for and is excellent for this purpose, especially for a pianist who will appreciate the nice action. Not a good choice for mobile rig--you can't split it into zones and there are a lot of sliders, knobs, and connectors that don't seem especially roadworthy. I'm very happy with it and am glad that an excellent graded hammer-weighted keyboard is available at this price point.
