Product review (4 stars): Works pretty well
Pretty good product, fairly easy to use, a bit awkward with length but that's to be expected.  Very surprised how clogged my vent was and now clothes dry in half the time.  Unfortunately I couldn't get my dryer away from the wall so I went in the vent from the outside. Seemed to work just fine although I don't think I was able to get the full length of the vent from only one side.  Will use again and would recommend.

Not 5 stars because it doesn't show or offer any way on how to connect to the drill.
