Picture shows both Fahrenheit and Celsius scales. I only received Celsius scaled. Temperatures didn't match between the two thermometers. There was a 4 degree difference. Turns out one of them was glued onto the scale wrong. Even though the item listed is inexpensive, don't waste your money.

This is exactly what we were looking for, so at first I was pleased, but when we assembled it we discovered that the screw is the wrong size.We improvized with some ticky tac and a rubberband.
