Product review (4 stars): Nothing much to say, it just works.
The contacts are solidly attached, the insulation is properly thick and durable, the plug casing is firmly attached and not loose.  The only down side is the slight annoyance of the clamps that come with it; it is one of those clip-on-one-side types that like to fall apart while installing it though once it is in place and tightened down it works ok.

The extra length of the cord makes it possible for more flexible placement of the dryer which I found very handy since a large pipe cap sticks up in the floor right where the dryer would logically go.
