Product review (5 stars): Great item. Remember..clockwise only!
Though we cleaned our vents, as far as we could  reach with a shop vac, we knew that wasn't adequate. This product showed us how much lint we had left behind. It was easy to use but PLEASE READ THE DIRECTION that says DO NOT put your drill in reverse to remove the brush. You might, like us, lose it in your venting. We ended up purchasing another brush head to push the first one through. <smile> Act in haste, repent at leisure. I would definitely recommend this product.
