Has anyone tried this? It claims to boost the speed of power windows. It was originally made for GM G-Body but the page says it also fits 4th Gen F-Body. I've been searching and haven't seen anyone try it (other than a crappy "after" video on their site). What does it actually do? Does it boost voltage? If so, wouldn't that burn up the auto-down module?

I've seen it listed on various places with mixed reviews. The good reviews say it helped. The bad reviews says the device didn't stay working for long.
