Product review (3 stars): Clamps are wrong size
The pipe itself seemed fine. But neither metal ring clamp fit my new LG washer (purchased locally). Installer (who does this multiple times a day with various brands and seemed perfectly competent) was baffled. That told me that the problem was the clamp, not the dryer.
Tightened down all the way, the clamp's circumference was still about an eighth of an inch too big to secure the pipe to the dryer.  If I hadn't been there, he'd have left it unattached.  I fixed the problem by using pliers to put a decent-sized kink in the ring clamp, thereby shortening it. It stayed on, but over time the tension will weaken and the clamp will become less tight and the whole apparatus may slip off the dryer.
