Product review (5 stars): Easy to use, and a very effective product
I purchased this product because I had been having trouble with my dryer for the past few weeks. It was taking me multiple cycles to dry loads of laundry, and was having a harmful effect on my monthly bills. I do own an older dryer so I was concerned that the heating element had possibly gone bad and there simply wasn't enough heat being applied to the laundry.

  Someone had suggested that I buy this product since I have a cat and dog in my home that both shed very heavily. I deemed this to be a cheaper alternative to replacing the heating element on my dryer unit, and much less expensive than purchasing a whole new dryer. I have a poorly designed dryer vent in my home that goes through the wall for approximately four feet, then takes a 90 degree angle upwards for roughly 4 feet, followed by another 90 degree angle to head out of the house for another six feet.

  With my initial pass through my vent I had trouble with the second 90 degree angle. It seemed as if the brush was getting stuck at the bend, so I decided to try and clean the vent from the outside of my home working inward. This was easily accomplished because of the ability to add and remove the 2 foot sections of the brush. As I cleaned the vent from inside I didn't have as much room so I was only able to use 3 or so extensions on the brush. When I went outside though, I was able to attach more of the extensions.

  One of the features that drew me to this particular product over some alternatives was the ability to attach it to a drill. Turns out that I had a very large chunk of lint stuck in the second 90 degree bend. With the brush attached to my drill I was able to clear the obstruction, once it was cleared the issue of lengthy drying times was resolved. Perhaps the only negative thing I would have to say about this product was that it was a bit difficult to take the sections apart once I had completed the cleaning. I was eventually able to get them apart and it stores away very easily.

  In conclusion, this product wound up saving me from as little as $50, to as much as $500 if I had wound up purchasing a new dryer. Cleaning your dryer vent is also something that should be done routinely since a clogged dryer vent is a fire hazard. I could not recommend this product any more highly.
