I have a bunch including an old woodsman, and some dome top ones. I got a Bee Z smoker last year and actually like it. I keep it plugged in all summer and just throw wood shavings in it, press the button and 30 seconds later I am smoking hives. I don't think the battery will last for doing 100s of hives, but for quick checks or small apiaries it is great. I don't have to light it and don't have to put it out before putting it back in the truck.
