Product review (5 stars): This product is amazing. We have about 20' long dryer vent
This product is amazing.  We have about 20' long dryer vent. I bought 12' extension rods. It is easy to use.  A good amount of lint was removed as we had not cleaned it for a few years. Before buying the product, watch the u-tube video on it. If you have a long vent pipe, this product is a must buy.
