All around great purchase!

Mobile mechanic here, I had another smoke machine that runs off my trucks air compressor but i didnt like how bulky it was. I bought this one and was immediately surprised by how much power this small package has. With its own air compressor and flow control, iy has already paid for itself as an integral piece of equipment on my truck as i spend my days inevitably getting to work on broken fords and chevys. I would absolutely by it again.

Worked as it should.

Easy to use to produce smoke, not clear on controlling the psi on it. Instructions could be better.
