LED Temperature Faucet Nozzle
Have you found yourself constantly getting burned by water when you expect it to be cold, or finding nothing but cool water pouring out of your faucet when you were looking for something hot?
With this LED Temperature Faucet Nozzle, you will never have this problem again!
This nozzle is designed to fit onto your existing sink faucet, without blocking the flow of the water.
When you turn it on, the water will glow with an ethereal blue when it is cool, and a bright red when it is hot, alerting you to the temperature before you ever have to stick your hands in it to find out.
