This was easy to install, simply unscrew the original faucet screen, screw on the LED screen and wah lah!.cool light up faucet. It lights up blue when it's cold, green as it warms up, red when it's hot then flashing red when it's really hot. I can wash dishes with the lights off in the kitchen using the light from the faucet led light.lol

We didn't like the multi color ones that rotate colors, it made me dizzy. So we proffered the blue light only. Then I saw this temperature color change and it made sense. Especially with children to teach them how to regulate the faucet. Try it, you'll like it.

Update October 2021: After about six months the blue leds went out, but I could do without them. Now the green LEDs are out and it's lost it purpose. I'll look for a different model.January 2021: I had some trouble installing because there wasn't enough thread to latch onto my faucet. Spent $5 on a connector from Home Depot. Using in bathroom where it adn take anywhere from 10-60 seconds for hot water to show up. Now I start using the water as soon as the light turns green. Psychologically it…

This was easy to install has a very slight drip where it connects to the faucet. Could be the threads on the faucet though. Very nice stream and light works perfectly. I use it on my outdoor sink. It’s nice and bright.

It works and is kinda cool but is plastic and I am not sure if it will last. It’s a a novelty that’s all. Thanks for attention.

This works well. It’s powered by the water flowing through it so it never needs batteries.Blue = Cold, Green=Warm, Red = Hot & flashing Red = Very hot.
