Product review (5 stars): Just what is needed
Like others, I could not believe how much lint I got from my dryer vent.  This is easy enough to use -- considering any task that requires moving the dryer and washer to get to the vent is unpleasant.

I bought the basic unit and the 12-foot extension.  I did not need most of it.  I would rather than they include one extra extension piece with the basic package; this would take care of most situations.

I cannot think of anything better than this, and highly recommend it.
