Product review (5 stars): Home owners - this product is priceless!
I don't write very many product reviews, but I do when I feel something needs to be said.  As for this item...It works really well and saved me at least 100 dollars to pay someone to do it and possibly prevented a fire.  Instructions were clear and concise.  I did find that some standard drills won't fit (as mentioned in the instructions), but I borrowed one for the occasion (same size as mine) that worked great.  The company states they will send you a free adapter, but I just didn't want to wait on the shipping.  I will order it for the next usage.  My experience with this product was a smooth one.  I mainly used the 4" brush and every single extension that was offered.  I didn't tape any of them together and didn't have any issues.  Just remember never to spin the drill counter-clockwise and all should be well.  Its probably a good idea to tape them anyway.  I like to live life on the edge. :) Originally I used a plumbing snake just to see how clogged my vent was and it was really bad.  That's when I decided to buy this.  I couldn't believe how much MORE lint I was able to pull out with this device because I got a grocery bag full just with the snake alone.  In summary, a dryer vent brush kit is something every household should own and use at least once a year.
