Simply attach the LED showerhead to your shower fitting as normal and watch the water change colour according to the temperature! If the water is hot it will turn red; warm, pink and violet; cool, blue and dark blue; cold, green. Whats more, the LED lights are illuminated by the force of the water so absolutely no batteries are required.
Never again will you have to step into a shower thats either too hot or too cold - simply wait for the water to turn violet and youll soon be in the pink! It's also a fun way to get those water shy children to have a shower more often.
