Product review (4 stars): I love this product
I love this product. It works great at removing the lint from the dryer and the duct work.  I also bought the extensions which also worked out great because the house I just bought has 18 feet worth of duct work.  The ends fit in my drill with some play so it's a tight fit.  The only bad thing I have to say about this is that the Shop Vac attachments didn't fit on the shop vac hose that I have. Other than that it is a great product.
