Product review (5 stars): I highly recommend this item not just for saving energy and time ...
Product worked well. Make sure you don't reverse the drill as ours came unscrewed in pipe and we needed to fish it out with a hook attached to a toilet snake. I should have taken pictures of how much lint came out because it was unbelievable the pile that we had. No wonder our dryer took so long to dry! And thankfully it did not cause a fire. My clothes normally were taking at least an hour to dry but after we removed the lint it took about 20 minutes and my clothes were actually hot! I highly recommend this item not just for saving energy and time but for safety sake!
