Product review (4 stars): No way to test them so I hope they work.
The hoses seem very sturdy, way better than the old hoses I had.  They are a lot stiffer so it was a bit difficult to get them on. I'm not sure if they'd be great for cramped installations. I couldn't figure out a way to test the anti-burst feature so I guess I'll have to take it on faith.  The instructions say they must be replaced after 5 years. I'm not that excited about that, I doubt I'm going to remember 5 years down the road to replace them.  All that said, if you have an upstairs washer where a busted hose will be an utter disaster, this may avert it. I also have water leak alarms at every toilet and washer. Cheap insurance.
