Thank you so much for this shootout! I've been suffering with a JLW (especially on Ms. Pac-Man), and all I could ever find prior to your review were lots of people saving that it's the best. At first I thought mine had bad microswitches, until I changed my technique and started sliding from one corner to the next to make turns. But turning that way hurts my (already injured) left hand, because it has to be pushed hard into the new corner to be sure that the turn happens. Sometimes I have to slam it hard enough that I can hear the case creak-- but anything less and I risk losing a life.
I think I'm just going to get a Leaf Pro instead. So much easier.
