Yeah stormer's banner advertises "89.99 brand new mylaps rc4 transponder", when they don't mention it won't work with all the systems. Their banner even states it's not a hybrid and they have a photo right next to it of an rc4 2-wire hybrid. It's not stormer's fault, it's mylaps fault and their monopoly of the transponder market. Noone wants to switch decoders for something cheaper, thus forcing everyone to buy the new uber " $120 hybrid rc4". Sickening.
