The Speed control is an extension cord dimmer switch.
I have a second fan for cooling but have never used it. For now it's a back up fan.
I have a slide on the drum that makes it either solid or perf by just sliding a handle.
Having to tilt the machine is the only thing that bugs me about this machine but it might be fixed now, I was a fairly early adopter.
The burner is silly good I think, never had issues with it.
