Product review (5 stars): worked great
Purchased along with the 12 foot extension kit. Attached with the provided vacuum adapter to my shop vac very nicely and cleaned about 20ft of flexible dryer vent without any issues. Also used the included lint trap cleaner and got all of the stuck lint under the trap area. The red rubber piece on the end of that brush fell off into the trap and I had to retrieve it with a long pliers. That was a big pain and the only thing I can complain about from this kit. Otherwise I am very satisfied with the results, which were evident in my shop vac afterwards. I would highly recommend this kit.
