I just bought and installed the Oxygenics shower head and the spray from it cant be beat, its absolutely wonderful. But then i was curious as to if it saved water, so i timed it and the original into a bucket and the Oxygenics used more water. I am still going to keep the Oxygenics though.
One brass fitting is all it takes to adapt a kitchen sink sprayer & hose in place of a shower head & hose. I have changed both my Camper & Trailer and it is great for saving water when dry camping, not to mention that it gives a much better shower experience by being able to give a squirt exactly where you need it!
