I'll give 10 stars, i like mine
What size compressor are you using?
Do you have to oil it every time you use it?
This is a good idea for ALL pneumatic tools, especially rotary tools. Air tool oil is reasonably cheap, you do not need a lot, and it can significantly increase the tool's lifespan.
I've been using my Rigid 21 Degree 3-1/2. Round head nail gun for about two months now. It is FANTASTIC. Never a misfire. Never a breakdown. It took only two nails to adjust the depth perfectly. It's my new favorite tool.
