Review on IWISS iCrimp Combo Pex Pipe Crimping Tool for Copper Ring with Gauge - 1/2 and 3/4-inch, ASTM 1807 Standard by Robby Fingaw

Smaller size so I can work in tight spaces which is a big plus. I had to set the trim to 3 to get past the pass/fail sensor. Increasing the setting required more crimping force. I think setting it to 2 would have worked (less crimping hassle), but I didn't want to risk permanent plumbing repairs. Again, setting it to 2 (which makes the crimp force acceptable) would probably work for more experienced folks - I wanted to be sure. Highly recommend for the price and love the smaller size.
