Nice quality, but if you're flowing nitrogen for soldering hvac tubing, you have to guess where 3 cfh is - not horrible, but it wouldn't kill them to put a line there.

It's a little harder to adjust for lower output but 5 extra seconds doesn't hurt for the price.

As stated it’s hard to adjust blow 10CFM. But was able to make it work.

Worked great. Wish it was easier to dial it in under 10 while brazing.
