Product review (4 stars): It does its job as expected.
Pros:
- Solid construction.
- Little to on air leak around it.
- Easy to adjust.

Cons:
- Edges can be sharp.
- Easy to install, just needed a flat head screw driver for the dryer hose.
- A bit expensive.

Bottom Line: It does its job as expected, I have had no problems with it at all, just wish I didn't have to spend that much on it but it seems that it will last forever.
