I really like my BernzOmatic and have used it for several activities other than the smoker/grill.
The portability and use for melting ice on the walkway or even burning weeds by my neighbors wood fence has been handy. I also always have a spare bottle as I use a hand-held MAP torch in the shop frequently.
