If you're looking for a good forearm workout, considering skipping the gym and go frame with this for a while. Prior to this, I'd never used anything bigger than a 16ga finish nailer. By comparison that was tiny.It took about 110psi to reliably drive 3-1/4" galvys into some scrap treated 4x4 I had lying around. That said, results weren't always consistent. I could never figure out a pressure/depth setting combo that would reliably sink nails to a uniform depth. Even using the same setup, wood and nails, some would be countersunk by 1/8" while others were that much above the surface. I'm not sure if this is typical of nailers, but seemed odd to me.With the exception of my table saw, I'm generally pretty lazy about hearing protection. However, this had me running for my earplugs. It sounds like a firecracker going off each time.Compared to more expensive units, build-quality seems on-par. A little rougher around the edges but didn't seem less sturdy. I was a little disappointed with the packaging. It was just loosely tossed in a cardboard box with the sequential fire trigger zip-tied on the end. I can see this potentially being troublesome when paired with Amazon's notoriously "rough" shipping.Overall, would buy again.***My Rating Criteria***Build Quality(47.5%) - 5.0 StarsEfficacy(47.5%) - 4.0 StarsPost-Sale Support(0.0%) - n/aPackaging/Presentation(5.0%) - 3.0 StarsWEIGHTED AVERAGE(100.0%) - 4.4 STARS
