I have had one of these for almost 8 months now and its FIRE!....Works every single time and the car feels great. Defiantly worth the $80. Trust me, you want one. Pushing the button every time is garbage, and for all you hippies out there...NO it does not affect the car in the rain. I still do 70 to 80 mph in the rain with ZERO problems. (I also have good tires)...
