Product review (5 stars): Perfect for tight installs
This is the perfect dryer vent for tight installations. I have 8 inches offset between my vent and dryer, which is just too sharp for flexible metal tubing to work.  Once I cut this down to size, it fits perfectly behind the dryer, taking up a minimal amount of space.  You will need tin-snips to trim the aluminum if you end up needing to shorten it.  Foil tape would also be a good choice to help seal up the seams after cutting it down.
