well ive been using mine for a couple weeks now. i can tell you this is a very steamlined system its cleared up alot of space for me. easily mounted anywhere, can be bagd with a machine baggy very clean! i have noticed a couple fluxuations in power and the wireless footswitch has stayed on after i let off it from time to time, minor stuff.the footswitch is very sensitive though so you dont have to think to activate it its natual but with a slight delay.overall extremely slick system and very pleased with it. i think i would miss my traditional gem if i ran more coils, but with the rotaries that little delay doesnt matter. have fun with your new toy eric03 youll love it!
