Product review (5 stars): Great insurance against laundry room flooding.
A friend had his not-too-old rubber wash machine hoses burst and flood his house; online recommendations were for steel braided hoses.  I think of them as a seat belt - you hope you don't need it, but you wear it anyway.  The new steel hoses fit fine, work fine, and I will never know if the old rubber ones would have burst or not - but it's one less thing to worry about - lifetime wash machine flood insurance for a few bucks.
