Product review (5 stars): works great
I had one before but after 10 years I lost it, this is exactly the same as I had before and it works as I expected it to, just remember a good cordless drill here is invaluable and DON'T RUN IT IN REVERSE, been there didn't like having to fish it out of the wall when the connections unscrewed; woops, the connections do get tight so using your drill in reverse with a pair of pliers after you retrieve it will help break the connections free.
as a side note I got a s&%t ton of lint out of the vent so here's hoping it is clear
