Pros
- Runs up to 1.5 hours of nonstop smoke per use, by the maker’s figure
- Made in the USA with a metal body and ceramic coil
- Warranty published: 3 years
Cons
- Needs a separate air compressor, so it is a shop tool rather than a driveway one
- No EVAP pressure setting or gauge is listed; EVAP safety depends on your regulator
