caveat emptor, let the buyer beware.
i bought one of the bellows type dusters a couple weeks ago and after several tries have come to the conclusion that it's cheap chinese crap. the main problem with it is that the powdered sugar won't feed out of the little hopper. you have to continually tap and shake on it which causes the cap to fall off the top and the tube falls off the bottom. even when you get it to work it's not like you're dusting the bees as much as throwing the sugar at them. this just pisses them off so you best have some gear on. found that out the hard way. maybe it's just me,if any of you folks have had better luck let me know. tia
