Do your poor fingers a favor and install the Greenwon Color Change LED Water Faucet. Instead of placing you digits beneath the running tap to test the temperature, this device serves as a clear indicator and won't risk burned skin.
Manufactured to be small and unobtrusive beneath the tip of your tap, this product is cylindrical in form and finished in shiny metal, allowing it to blend in with many different types of plumbing fixtures. Inside is a filter, tiny colored lights and sensors that instantly switch on once water pressure is applied.
The flow might start out as a comfortable blue, signifying a range of 33? to 41?. If you shift the tap for cold water, a green glow will be emitted from 32? and below. The LED Water Faucet notifies you of 42? and up with a red hot beam.
