after moving and adjusting the weights to every known position to limit the shake on this thing with not much success, I just ordered a few of these speed controllers. I have TWD:Premium, and with the red coin taker shaker, its just too strong. I will get this installed as soon as it arrives and let you guys know how things turn out.

thanks to all that have posted in this thread.

i can say this, I have the pinball life one in my IronMan:VE and haven't had to tape or do any mods of any sort due to rattles or shakes. I would return both of red tremors to coin taker, but its not their fault. Im sure these will be fine once I tone them down.
