Product review (4 stars): Not Bad - Price could be lower
As a homeowner, and dryer owner, for over 30 years, I have installed - and replaced - a lot of dryer vent hose.
I do try to clean my dryer vent at least once a year. That's what lead me to MagVent.

Every time I have to move the dryer, my previous set up using the expandable semi rigid aluminum duct needed to be replaced.
I just checked price at Home Depot for semi rigid. $11 for 8 feet.  Let's see ....... 30 years times approx. $11 equals $330.

The price of this product does appear high, but build quality is above the average for standard dryer vent products.

For installation, I tried using a laser pointer centered in the dryer vent by hand, but I found that, while I got the horizontal axis right, my vertical axis was a little low. Noted this by checking my layout with a steel tape.  A torpedo level with laser might be just the tool for this job.

Installation instructions do not specify how far forward from the wall the dryer can be for vent to work.  My install went very well.

Just installed it yesterday. No lint leaks noted.
