Review on 🚿 3 Color LED Hand Shower with Temperature Display, Chrome Finish, 4.25-Inch by Scott Maddocks

I like this thing but thought it was broken because I didn't know how to use it. The water flowing through the unit generates electricity to control the lights and thermostat. Low water flow causes indicators to flash. Adjust the shower head to increase the flow so it doesn't flicker. If you don't need a 'water saving' showerhead, remove the gray plug from the gray plastic connector attached to the water line coming out of the wall. I used pliers, but small pliers can work. I need reading glasses to see small numbers. A simple trick allows me to see the temperature on the LED screen. Make a fist and bring your thumb to your eye. Look through the small hole in your palm. The LED screen is as clear as the glasses. I like the water temperature from 101 to 103 degrees.
