The small size kit has the same solenoids that can be purchased with other small shot kits. I have heard that Peter Paul Electronics is the common supplier of solenoids with custom labels being the difference for several kits. I've looked around while at the Summit retail store here locally and compared the solenoids. At least two other kits have what looks like the same units. Zex also sells a large hit kit with the higher amperage and larger solenoids. The 75-125 hp kit is what most people think of with Zex but they also have a 100-250 hp Gen III High Output System that has the large, high amperage solenods which require a relay. The bad rap given to the zex kit is that people are not comparing apples to apples. The orchid color may be gaudy but the finish and quality of anodize is quite good. Their purge hardware kit is really nice IMHO. I own one and wish I'd bought two for my other nitrous setup. The $2 activation button is my only complaint. As for customer service, I needed the expen$ive NMU replaced under warranty. I had to go through a few hoops but was always able to talk to a tech or CS rep who could do something. They answered all but one of my questions via email and were always available over the phone. You hope you won't need warranty service at anytime with anyone but shat happens. I guess everyone already knows that ZEX is Comp Cams so you are going to lose some of that warm/fuzzy relationship but at least in my situation they have the cash flow to be able to make an expensive component replacement.

Zex, I love mine, easy plug and play setup, Hallass runs a zex dry kit with a 108 Dry shot, he's running a 11.86, with a tune, longtubes,converter,lid. My choice all the way.
