> Their copy on Kickstarter says it pays for itself in 2 years. That is highly dependent on what they calculate for prices and what shower heads they compare to. Their main website shows savings examples of anywhere from $89.05/year (Miami) to $399.68 (San Francisco) for two nine-minute showers per day. This is presumably comparing against a 2.5 GPM head, since their head uses 0.75 GPM and they claim a 70% reduction in water usage. Comparing to one of the many 1.5 GPM or 1.75 GPM heads will obviously lead to significantly less savings. > Think of it like Tesla for shower heads Big difference between Tesla and Nebia: Tesla was going after a market where the current participants didn't really care about pushing the state of the art; Nebia isn't. Kohler and Moen in particular have been developing and pushing low-usage plumbing fixtures for a while.
