I use the Primus IQ (see my sig for my rig) and have had virtually no problems with it. The only thing that did happen was the boost button got stuck when I had to hide it in the console (I was in a questionable neighborhood) and I think it got bumped pretty hard when I tossed it in there. I just grabbed my pocket knife, pried up the button, and all is well again...
