Product review (5 stars): Worth every penny; a simple, effective tool
Using this and two 12-foot extension kits, I cleaned out the world's longest dryer vent. For some reason the builders did not think to take the shortest path from the laundry room to an exterior wall. This means we have a 30+ foot vent. The dryer was taking longer and longer to dry our laundry. There was still air flow at the outside vent, but not enough. I used the lint eater and pulled ~3 lbs. of lint out of the vent. It took half an hour because the vent was so long, but now we have more than double the air flow at the outside vent. We will no doubt recoup the cost of this in reduced electric bills because we won't have to dry every load twice.
