Works perfect!

Was wondering if my digital thermometer and heater was working so decided to try this as well. Found out my digital has been working perfectly! Never hurts to try low tech as well.

Easy to read

I like the GREEN ban on this thermometer. At a quick glance I know temp is in a good range.

Tiny increments and numbers may be hard for some people to read. Keeps accurate temperature to verify against our digital unit.

Great Minimalistic Thermometer

This is a great little thermometer that takes up basically no space, is highly accurate, and looks aesthetically pleasing. I'm glad I bought one for each of my tanks.
