Flexable ""Green hose"

My neighbor across the street had one burst right at the sprayer end. She got quite wet. The first one I bought leaked and I took it back to the store for another one. The second one started coming loose near the sprayer until the inner hose created a bubble before I turned it off. I wrapped that end with Duct tape and it's held so far. I think the hose is crap, but a great idea if it would hold together. I wonder if the coiled hoses might be better for the RV crowd? Although I have heard that only the wite hoses are approved for drinking water.
