It sucks. We got one ~4 months ago, used it only to connect from the spicket to the weaping hose (4' distance) never pulled out etc. and it busted about 45 days ago
I got one about a month ago to use in our garden and haven't had any issues so far.
It gets used every other day or so. It does expand and then contract. I am not sure how it will hold up in the long term since it does seem sort of flimsy.
Ours expanded and contracted as promised, I think that's what ultimately breaks it. Its an outer coat over a plastic-y tube and it feels like the tube detached from the threaded end. We weren't dragging ours out and stretching it like normal use and it still broke.
