Title: Iffy
Review: I personally don't like these thermometers. I got this one when I bought a tank. It's not all that easy to read. Sometimes, three bars are colored, making you wonder "Which one is the right temperature?" It doesn't have a very high range, either. I suggest a real thermometer. They're easier to read and come in huge scales. What happens if you heater overworks and the tank is at 100 degrees? You can't tell. It happened to me before, and let me tell you, it was horrible. Like I said, don't get this one. Use the $2 you'd spend on this one to buy a real thermometer. Bigger range, easier to read, and comes at about the same price.
