Amer Thermal Instruments Liquid Crystal Vertical Aquarium Thermometer: Compact and Efficient Review

Fairly easy to read and accurately reads the temperature of my fixed temp aquarium heater. So either they are both right, or both are equally wrong. Easy to remove and stick on the aquarium.

It was working until I carried it into the room from the post office but when I put it in the tank it just sits against the wall everything is constant greyscale. Ten points for the suction power, it doesn't come off the walls of my tank no matter how many times I clean it.

I bought this for my 1 gallon aquarium where I have a male rooster. This thermometer works very well. It shows the pace. exactly in Fahrenheit (which I wanted). It is very easy to apply to your aquarium (just peel off the sticker from the back and stick it on the outside of your aquarium). It's small and the perfect size for my 1 gallon aquarium.
