Very well built and robust, good weight to it, very solid. Has 25 keys and a variety of features including rotary encoders, pad triggers. AFAIK the free software was never used, so it may still be available however not sure if it can still be redeemed at this point, I would say assume not, and if is then take it as a happy bonus. It has seen light use, keys are very responsive, there is some yellowing of the keys from sunlight, however there are ways to reverse this if it bothers you.
