I bought this as an open box item, and it was just as described. After two weeks I'm still trying to learn the ins and outs of this controller, but for the money I am really impressed. The ribbon and pitch bend wheels are well placed, the keybed feels solid and even, and so far it has done everything I ask it to do. I am using it with the included Ableton Live Lite and included Xpand 2, etc., on an older Mac Mini, and it is an amazing combination. The controller is very lightweight but seems solidly built. The software for editing the controls is a little weak, but it is a great value despite that -- I find that the default mapping within the supplied tools is pretty good. I was concerned that 37 keys was too few, but haven't found that to be the case with the nicely placed octave and sustain buttons. And wireless out of the box, with included USB receiver dongle? What's not to like? I couldn't be happier!
