No not at all. It’s fuck’n awesome.
And then buy 200 proof ethanol and it’s super clean and it is also what is used to clean cocaine after acetone wash.
One full cup lasts 30 minutes. Warms 2-4 ft diameter. It can also be used inside but it’s sketch of course. I have done it. Just don’t bump it or fuck around. Lol seriously not funny.
Other than that…
It’s worth the money.
