Save Water with “Traffic Lights”

If you are a enviromentalist and have awareness of saving water, this gadget may be quite practical for you. You just need to put it at the bottom of your shower, and it will monitor the amount of water that has flowed out from the shower. When you are using too much water, it will inform you through the LED indicators with colored traffic lights. If the traffic light is red, that is to say it’s time to stop, which is nearly the same as traditional traffic lights except that the gadget can be reset by yourself. It’s a good gadget but I have no idea how much “too much” is. Just get one in hand, and I think that will be clear. This gadget will cost $8.
