Review: Flexibility and durability - I had to replace the old dryer vent and chose to try this new type, I was not disappointed! It's easy to install but a bit tight fit. But, not impossible to do but just a bit small for a 4" size. If you carefully twist it, it will fit and hold. My vent was in the crawl space so I fed it from inside the house then lucky for me I only had to grasp the other end a few feet away from the access door and hook it up to the outside vent assembly! I would recommend it.
Review: Nice Hose - I ordered this but was a little hesitant after reading the reviews.I am glad I took a chance anyway. It is thicker than the ones from Lowes like I had before. The wire attachments are very nice and sturdy. It was not hard to install. So I am very happy with this purchase. I really like the gray color as well.

Needed an extra-long dryer duct to get from new dryer location to existing wall opening. So far so good - very easy to install and have had no issues to date.
