For the price, this is the best 88-key weighted keyboard controller out there! OK, so its not quite as good as a 'Kurzweil" keybed, but it is the next best thing, ...responsive, stable and light. The next best feature is its ease of configuration using either the on-board color LED screen or (better) using the on-screen GUI app to do it, ....and having jacks & provision for three (3) switch controls and 1 expression pedal. I also decided to get the optional snap-on laptop shelf for my laptop, which has come in very handy. The only con I could say is that I am not a fan of the joystick-style controllers on the keyboard, but I am using this primarily for piano, electric pianos, and organ anyway.
