Sorry to say I havent reached the point of using it. It looks to be of excellent quality, as good or better than the hose I just removed as part of my condition inspection. Sorry not to be able to add more at this time.

Its a perfect hose and quick delivery. Wish the wall was bit more stiffer to ensure that it wont collapse at bends. Hope it gets harder over time.
