I buy the 25 ft rubber hoses and use quick connectors to hook them together as needed. Works out pretty well, because that way you're not always dragging around a 50 ft hose, and the connectors sort of swivel too, so it doesn't get so twisted. AND I put in in-line shutoffs so I don't have to run back to the faucet to turn it off. But the last one I bought was NOT as good as the previous ones, even though it was supposed to be the same model and brand. Darn thing kinks! Anyway, I've been curious about those expandable hoses. Think I'll ask DH to pick one up when he goes to town.
