Product review (5 stars): Excellent product
This systems worked much better than I expected.  It was easy to use and I couldn't believe how much lent was removed from my exhaust.

I only had a small 3.5 gallon shop vac which had a very small diameter hose.  It was too small even with the reduction adapter that the system came with.  I simply used duct tape to seal the vac hose onto the plastic dryer vent adapter and it worked great.

The brush fits the standard dryer vent nicely and the extension rods were just flexible enough to easily go through corners.

The additional "bottle" brush worked very well for cleaning out the inside of the drier around the motor and also in the back of my fridge.

This system works just like it should.
