N1-Water Stream Faucet LED Light RGB Temperature Sensor Automatic Changing Shower Spout Sink Tap - Red, Blue, Green (2 Pack), New

it works well, red when its hot water, green when its warm , and blue for cold temperature, my kids loves it

Use teflon tape when installing to prevent leaks around threads. Works great , three colors according to temp: cold blue, warm green, red hot. More water pressure the brighter the led glow . Looks great in the dark but the only down side is kids want to turn on water often for light show. Gonna try temporarily on shower stem as puts out a strong spray and lights up well on full throttle. Well worth money but still a gimmick, impress friends, family, and especially kids . Buy 2 and save Give as gift
