Product review (5 stars): Works Great for Dryers and Portable Air Conditioner's Too
Rather than using this for a dryer hose I'm using it for a Portable Air Conditioner exhaust vent hose in our cabin and it works great.

The quick connect flange installs onto the pipe on the wall with 3 screws and allows you to connect and disconnect your dryer house with ease leaving you with a clean appearance when the hose is not connected. This quick connect dock allows use to connect the air condition exhaust vent house during the summer and then disconnect it during the winter time.

The Dryer Dock solved two problems for me

1 - The wall I wanted to put the portable air conditioner against did not have a window so there was no way to vent the AC using the supplied window adapters

2 - Drilling a hole and installing a vent was easy but in the fall and winter time when the air conditioner is not in use the vacant dryer vent pipe looked ugly. I made an adapter cover which allows me to insulate the vent pipe during the winter and provide an attractive wall cover during the fall and winter when the AC unit is not in use.

Considering this Dryer Dock is just to simple pieces of plastic it is a little pricey but it does do the job so in my case it's worth the money and I would recommended it to anyone who wants to connect a Dryer or Air Conditioner vent hose and leave a clean appearance when disconnected.
