Product review (5 stars): Sturdy, great quality, not too heavy
Much better quality than a vinyl or "crinkle" hose; safer hose as well.  Easy to install, not too heavy (it is of course heavier than the vinyl or crinkle hose, but I prefer quality/safety).  I installed this to an interior lint trap with no problems.  I advise having two people to "pull out" the hose to the length that you need; easy to trim with scissors.  It costs more, but I think it's worth it.  Recommended.
