Product review (5 stars): Absolutely love it!
While getting ready to get a new washer and dryer, I figured I would get a setup like this to make moving it around a simple task. I know what you're thinking, "How often do you move the dryer?"  Well as I am working on the house, getting ready to redo all of the plumbing and replacing an old fuse panel with a new breaker box, then redoing the floor and cabinet work, I find myself wanting it moved quite a bit.  This makes it a piece of cake.  Just a little turn counterclockwise to disengage the latch and it comes apart without a hassle.  The way it's designed, it's sealed pretty tight and have not had one issue with it leaking air or lint.  One half stays securely connected to the house and haven't had any issues of unwanted disconnects either.  I'm glad I bought this and am sure it will still make my life that much easier in the coming months as I finish up some projects.
