Like others, we have a few. our main hookup is on one that has been in AZ and Fl sun for two years and still works great ( so much for the durability question). The outer cover is a bit faded from when it was new. The zero-G isn't one of those cheap accordion hoses but does shrink some and is lightweight and flexible. I keep ours in a small wash bucket when on the road. As to water pressure, I'm not sure about the fittings but the hose itself , I think I read ,was rated to 600PSI ! a little overkill for the use
😉 so I wouldn't worry about water pressure on the hose. They are rated for drinking water.
Most of our friends have switched from the old white hard hoses in the last couple of years. They wouldn't switch back.
