Product review (5 stars): Does the job, well made
This had enough configuration choices. It is well made and not fragile. The default way of using this is to push a rotating brush on a rod from the outside dryer vent exit down to the in house dryer. We were not able to get the brush and rod into the vent from the outside because it was a tight right angle. Instead, we worked up from the basement by going up aways, pulling the brush and rods out, then going back in again a little farther, then repeat until reaching the outside vent exit. We pulled the lint out and piled it up until were through, then vacuumed. The kit provided a way to run the brush up while collecting the lint into a vacuum or shop vac; we found it simpler to clean the vent, pile up the lint, then vacuum the pile when done. We also replaced the flexible venting from the dryer to the external vent pipe; this replacement is normal maintenance for someone with aluminum foil venting. All told, it took us less than an hour.
