Product review (5 stars): Nice product, works as advertised
Created nice tight connection without requiring much space between dryer and wall just as advertised.  I thought the design was far superior to a different brand I purchased at Lowes/Home Depot for a previous installation.

Installation was easy, but as discussed in other reviews, have metal tape (not duct tap) ready to seal up the ends once you've determined the correct length for the ducting.  The instructions say that you can leave the excess ducting, but odds are if you need this type of connection, you probably don't have room for a bunch unused ducting, so having tin snips available is a good idea.
