Query: Great, great tool

What a difference this made for our dryer. This is an excellent tool, well designed, well built, rods are very sturdy. I did have a pretty severe blockage that I had to actually take part of the ventilation system apart to get too since the brush would not go through, and the blockage removal tool was missing from my box (but the company got right on it and is shipping that out to me). It's possible I would not have had to take anything apart if that removal tool was there. But the most amazing thing is how clean it gets the vent. The brush got so much lint off that the 16-gallon shop vac got plugged up on the other end. I highly recommend, there can't be a better way to clean this yourself and our dryer is now twice as efficient.
