I got a bunch of usage out of mine and it works flawlessly. Ife done probably 100 or so launches with it and id say 2-300 no lift shifts all work awesome. The no lift shift is probably my favorite part about the whole system, the 1-2 shift can be a bit tricky and I usually still let off on that shift, but everything else shifts smooth as butter.
Im sure James will chime in here shortly.
