Product review (4 stars): Well made, but installation instructions should be better
I suggest that you really scope out your particular dryer, home set-up to make sure that this will work out well for you.  In my case, the dryer has a recess along the bottom that should allow a dryer vent like this to get the dryer close to the wall - however, the wall vent hookup is located about a foot higher - so the recess won't work as intended.  Due to this, I can't get the dryer much closer to the wall than was possible with the expanding foil duct hose.

This vent is well made, but the installation was more complex than it should be.  I have a lot of DIY home improvement experienced, including doing some HVAC duct work, which was useful for modifying the vent periscope to fit my situation.  The instructions don't really give much help about the best way to modify, so if you haven't worked with duct materials like this before you may want to get help or do some research.
