Great machine to find leaks.

The flexible stream meter is great. My past smoke machine didn't have a stream meter and I can say it is good to have the option to unequivocally change smoke yield. It is by all accounts fairly made. It has a to some degree hard shell to it and indeed, which ought to give extraordinary insurance to the code peruser. Works impeccably as planned. Immediately found two broke hose spills. It's not difficult to utilize and the cost is correct. I really do contemplate whether a form that utilizes more strain to push the smoke through would be far superior.

Richard Wright
Ease of use

Produces good amount of smoke, built in compressor, quiet, easy to implement, and quick turnaround time. Useful for finding leaks on automobiles.

Must have for diagnosis.

Love this little machine. Any baby oil works well. I was able to smoke my fuel tank to narrow down the EVAP problem. Purge Vent Valve was leaking. 1 use already paid for itself.

Luz Olivares

Works good if it’s 12 to 18 inches within the product

It was missing a few screws. Use it for various projects paint, caulking, drywall,
