Product review (3 stars): Good Idea but
Keep this in mind before ordering this Vent Hose Quick Connect.  Do you have enough room behind the dryer for it to fit and make all the connections?  It robs you of another 2" or more of space if you can get it to fit properly into the existing metal duct.  Mine would NOT fit into the existing metal wall duct, therefor I was not able to install it.  If you look at their installation photo, you will need more space behind the dryer for the elbow turn into the wall and into the dryer.  If space is not a problem, this might work for you.  My star rating probably should have been lower, except that I like amazon.  The cost of the dryer dock vent hose quick connect does not make it worth while for return shipping, which the consumer has to pay.
