Worked excellent! I tried a different less expensive brand first and it failed miserably. It just couldn't make the 90 degree down turn in the vent. Determined to get the dryer vent cleaned out I bought the Deflecto Dryer Duct Cleaning Kit and it worked flawlessly. It ran all 12 feet in the kit with out binding or hanging up and made the 90 degree turn in the dryer vent without hesitation.  This product did an excellent job cleaning the vent and performed above my expectation. If you need to clean your dryer vent, start with this product.
