Product review (5 stars): Your won't believe it until you see it for yourself - amazing
This product was amazing - people will not believe how effective it is until you experience it.  I brought this product to bring to Belize where have a condo - my dryer needed 3 dry cycles to fully dry my clothing.  I looked at the vent and there was a 2/3% obstruction in the vent pipe. I was very skeptical about this product but though I'd give it a try.  I was completely amazed.  We hooked it up to a shop vac and boy was I surprised when I looked in the bag - it filled up like a pillow that's how much lint it pulled out.  The piping to the dryer from the outside vent was very long so there were not enough extension to make the whole run so we had to work it from both ends (we did each one twice) but it work perfectly.  We had to use the larger, stiffer brush.  Very pleased and would recommend.
