Review on Efficient 18 Gauge Powernail Nailer for Engineered Flooring by Scott Ward

I bought this gun for repairs. I was running 3/8 hardwood and had about 100 square feet when the spring on the nail locking mechanism broke. It fell apart as you can see in the photos. Revain will refund the money, but it is not possible to replace my time with work that should have been completed on the day it was interrupted. Revain gets an A+, Powernail, well that's a failure. I may have been unlucky enough to get a defect but on the plus side it was easy to use, light weight, fast, easy to adjust to different thicknesses of material but reliability is a must. I don't know if I'll buy another one, but I need about 20,000 nails.
