When your home is smart, will leaks go away?
At $800 for one of these gadgets, I don't think most people will be interested. The info might be interesting, but there's no way it would help you to save enough water to be worth the price. They claim that you can save $300 per year through use of the gadget, but that's completely unrealistic. It might be possible to save that much in a decade, but you could save just as much without one of these gadgets by just using as little water as possible!
