Your faucet just got a whole lot cooler. This smart LED attachment transforms your tap into a color-coded temperature guide — glowing blue when it's cold, green when it's warm, and red when it's hot. It's the upgrade your bathroom or kitchen didn't know it needed.
3-color temperature glow — blue (cold) / green (warm) / red (hot)
No batteries, no wiring — powered entirely by water flow
Twist-on installation — fits most standard faucets in seconds, no tools needed
Kid-safe — instant visual warning before little hands hit hot water
