Review on LCD Digital Aquarium Thermometer, 2 Pack Fish Tank Thermometer with Large Touch Screen - Accurate Temperature Readings for Terrarium Amphibians and Reptiles by Christine Zuniga

Accurate and easy to read. large print. Some reviews mention how disappointed they were that only Celsius was displayed. I was able to switch it to reading Fahrenheit on the touchscreen with no issues. Once it sticks to the tank it will be a snug fit so make sure you want it where you put it. The only downside is that it didn't include instructions on how to set up high/low temperature alarms. However, it's pretty easy to figure out when to start messing around with it.
