I would take much longer showers without the Oxygenics as the water stream didn't have enough pressure to quickly rinse the soap off. With my Oxygenics both my DW and I can take a Navy style shower (just twisting the knob off, using the small stream that remains to help work up a lather) on one tank of water. Our Aliner only has a 10 gallon fresh tank (and a 6 gallon heater.) With our old shower head we would each use almost 10 gallons per shower. Since we only have a couple 7 gallon aquatainers to catch the waste water, (no grey tank) this was a problem, requiring the non showering person to switch tanks in the middle of the other person's shower.
