Used 2 of the 25' Zero G all of last season, they are still good for this season. I won't go back to a white hose. Mine aren't even the marine grade, bought the standard hose at Lowe's. Says on the package that is drinking water safe. So far me, the wife and kids seem unaffected. Honestly, we don't drink water from the tap at the campground anyway, mostly drink bottled. I also bought a lowes 5 gallon bucket at the same time, store all of my water stuff including hoses in that.
