Product review (5 stars): Better than I though possible.
This product is fantastic. While it recommends that you replace foil and plastic vents for the dryer I had no choice but to try it on our foil vent as the dryer just was not drying. I was very careful feeding in and back and the results were AMAZING. We have nine dogs and the dog hair gets everywhere. In three passes down the vent using longer and longer rods to feed the brush into the vent I got enough hair out to build a whole new dog. The dryer is now drying like it was brand new and instead of three dry cycles to get clothes dry it is doing it in one. The powere savings alone will cover the cost of this set very quickly.

I then tried the brush for cleaning under the fridge and oven, same results, masses and masses of hair. Rather hard to control the movement under those appliances but the results were great.

I whole-heartedly recommend this product and am going to make sure that I schedule to run this through the vents every 6 months just to stop such buildups happening again...
