I loved this hose until we got down to 4ºF and it froze. I left it plugged in and the next day it was 18ºF and still frozen, so I guess it only works into the 20's. Better than nothing, but it up to you whether the added 15º is worth the money. This hose is of course very stiff and hard to get uncoiled (i'm still working on that). This hose has a 2 yr guarantee as opposed to the brands 1 yr.
