Oh yeah, you gotta be careful in choosing them. I’ve used the predecessor to the longhorn for years, and if maintained they work really well. The biggest problem is that it can be hard to keep a constant temperature on windy days. The thin steel construction lets a lot of heat dissipate into the wind. That’s why the expensive custom smokers are so much better. They use thicker gauge steel that holds onto the heat better.
But the longhorn smoker is still a decent buy. Most of the other cheap offset smokers out there are complete crap.
