Nothing's worse than stepping into a freezing cold shower. Sure, you could have checked the water with your hand to make sure it was warm enough to enter, but who has the time for such things? Time is money, people!
That's why this lighted shower head is so great. It changes color with the temperature of the water, ensuring you know by sight exactly when to get in. If it's white, it's like icewater. Blue, it's lukewarm. Purple, it's just right. Red? Call the burn ward. Now you'll always know just what to expect when you jump in the shower without checking the water first, which is something that I can only assume will include your quality of life tenfold.
