Color Changing LED Shower Head - Temperature Sensitive

Do you hate stepping into the shower before the water has warmed up? Then you need this! The LED lights in the shower head are powered by the water current (bonus! no batteries needed!) and change color to correspond with the temperature of the water. 3 colors will display depending on the water temperature: * GREEN: <=32C / 90 F * BLUE: 33-41C / 91 - 105 F * RED:42-45 C / 108 - 111 F * FLASHING RED:>46 C / 115 F Your water will glow! Most shower heads just dispense water, this one also provides a nice illuminated shower experience, and saves you from doing the Chilly Water Booty Scoot! Easy retrofit installation, just twist off your existing shower head and replace with the new one. 3/4" screw diameter fits most standard shower hoses. Dimensions: 22cm x 8cm x 5cm (L x W x D) 8.7" x 3.1" x 1.9"
