Product review (4 stars): Clean your dryer duct now!
Well it was a nasty, nasty, unpleasant job, but all 12 twisty feet of our dryer duct passages, all alike, are now clean and functional. This thing works as long as you remember to *only* run the drill clockwise. Don't run it the other way, even by accident even for a second. Otherwise, parts can come unscrewed and fall off in your duct. Don't ask how I know this. Finally got all dust and parts out, but for a while there I thought I might have to take the duct apart and fight the grue in hand-to-hand combat. Looks like this clean-out will become an annual tradition in this house. Who knew dryers were such a pain in the backside?
