"THIS. IS. AMAZING. This thing is seriously the best drop in unit I've used. I own a jack, I've used a wolverine, I've used a hydra, I've even tested an F1. And this is by far my favorite. I've got 1 gripe but everything else is positive. So when I first ordered the mkII I was really excited. It arrived and I was super excited to install it and get it going. But when I began testing I noticed a small leak from the top hole by the solenoid. I contacted protech who gave me a few things to try before having me ship my product back to them. I ended up shipping it back and having it fixed. Not only did they ship my working product back, but they also shipped a sample of their "proloob" that they are currently in the making of. So onto the pros and cons now.
Aluminum nozzle
Drop in install
Cheaper than other drop in units
Easy to maintain
Low Dc(dP on p*) apposed to a very high dP on a jack
50RPS max to keep speedsofters to a more reasonable limit

My first one was defective
