Not worth it – Instant Supercar Review

This is a neat idea, but it is poorly executed. First, the sound is grainy and artificial, and the looping is very choppy. Second, the app is almost entirely incapable of sensing the car's motion. It seemed to behave almost randomly. I'm disappointed in myself for having spent money on this item — and I am forced to wonder whether the other raving, five-star reviews are astroturf. Don't take my word for it, though — notice that the infomercial on the app's website contains no demo and no samples of the sound.
