They had a floor model at best buy that I tried. It works fine, but does not give you the feel of a real pinbal machine. I have to say they are slow, unresponsive, weak, and cheap plastic feeling...not to mention the ten seconds of music that loop over and over get annoying.
It would be fine gift for the kids, but if you want to create the authentic pinball experiance, I think it is better to save your coin for the real thing.
