Falls A Little Short Of Expectations
By Christian H.
Michigan
Purchased 12/31/2023 |
Review Posted 01/23/2024
I want to really like this compressor but it falls a little short in a few areas. It is very quiet and runs in the cold which is nice. Fills up quickly but runs non stop with a small angle grinder with a 2" sanding disk. With a 3" cutting wheel it stalls out. The frame of the unit is steel and not aluminum and probably adds a few extra lbs which I don't like and probably not worth it to get the aluminum tank. There's no cord management or small accessory storage either. So it's not very portable, powerful, or feature-filled, just quiet which is okay for me since I usually work late into the night. It'll make a great unit for my paint sprayer and general use around the garage but really could have spent a 1/3 less for that.

Overall nice unit. Quick to recover, even under heavy use. Sprays texture, well positive, it will drive nails. The only down side is its heavy. I'd you don't need the capacity get the single tank unit.
