Product review (3 stars): It seems like brittle plastic
I hope this thing holds up.  It seems like brittle plastic.  I didn't realize that its one of those collapsible/expandable type hoses. I hooked it up to the washing machine in a collapsed state because I only need a few more inches in length to reach the drainage pipe with some slack.  When the machine started draining, the hose expanded on its own.  The hose is working just fine as of now.
