Black Widow HVLP Spray Gun

I use the 20$ purple HVLP gun from harbor freight and it’s worked well enough. Used it on a few engine compartments. Curious about the black widow one myself.
That's because it is a China knockoff. A good one. My friend's body shop keeps a few of them new in box for when his good gun is down or shooting more than one car at a time. So he can shoot one thing walk next car an shoot again for no down time. Seen him shoot 3 jobs same time one to next, to next.
He has shot many a candy job with purple guns. He stocks House Of Color he shoots it so much.
