Efergy Shower Timer

If you don’t like the idea of wasting water, you might want to check out the Efergy shower timer. Simply put, this gadget will take an initial measurement of how much long it takes your shower to go through a liter of water, and after that, you’ll be able to measure the amount of water you use, or set the timer to notify you when you’ve used a certain amount of water. It’ll set you back about $13, but perhaps you could save that money back in water bills?
