Product review (5 stars): Unlike anything else I've tried
Unlike any dryer vent I have ever seen or used before!  Although it may be up to 8 feet long, it can also be very short. This vent is rigid in cross section ! I am astonished that I cannot find this product in local stores, and am thankful it is available through Amazon. Every vent I have previously purchased has crushed, torn, has fallen off it's connections, or been disfigured at or near the end clamps. With this vent, I am successful with a friction fit at the ends, and can clean the interior of the vent without concern. This product is ideal. Read my other reviews and see that I can be a naysayer. You don't detect any negatives here, do you? There is a reason for this. This product is great. If your installation requires this vent to be crushed, get something else. This product will remain rigid in cross-section even when shaped to match your installation.  The inventor should be proud.
