Got mine by supporting its development on Indiegogo; I've been using it for a couple months now. A lot of shower wands have several different spray patterns, and I though I might miss the variety. I'm finding that's not the case. The standard spray really relaxes me, and I can definitely feel the difference in cleanliness. Using the same shampoo I've been using for years, my hair comes out squeaky-clean, where before, it really wasn't. Similarly with my skin, and spraying the glass of the shower stall at the end of my shower leaves it cleaner too, as evidenced by water not beading on it as much as if I don't spray it. It's interesting that I find the mist setting to feel much cooler than the spray setting; I have to adjust the shower temperature up several degrees to have it feel as warm. Perhaps the best summary I can give is that before getting this shower wand, I really didn't look forward to my showers, but now I do. After a shower, I'm not just clean, but more relaxed.
Clearly, the price of this shower wand is enough that a lot of folk will think it too much, but consider that if a family of four each take a shower a day, then ten cents per shower would pay for it in a couple years...and that's not accounting for the potential savings in hot water.
