I've got this, and yes, it's crap. The goggles that come with the kit
are especially crap!
I got it to do a load of trim work throughout my house and it has
performed admirably and without a single jam. As far as I'm concerned I
purchased it for this single job which it has completed without issue.
It has saved me a ton of time, has cost less than renting one for 2-3
of weekends and I'm left with a nailer that will be useful for
occasional use so it has more than met my expectations.
At the end of the day it's still crap and probably wouldn't last 5
minutes with a trim carpenter but it does just fine for my use.
