Cons: It smells real bad when lighting and turning off. I extinguish then I carry it onto front porch. I light it, let it glo and carry it in. No bad like that. The tip over extinguish is very sensitive and will trip sometimes for practically no reason. And it stinks up the whole house. Wick had to be replaced after a years use. If you can get used to the stink it will burn for 16 hours on low setting. It keeps 3 rooms real toasty 600 sq. ft.
