Title: Don't waste your money!
Review: I purchased this item from an online pet store. I liked the fact that it is a good size and it is easy to read. However, it only worked for a year. The unit continuously malfunctioned even after installing new batteries figuring that would have been the problem. Unfortunately it wasn't. It kept saying it was over 100 degrees in the tank. My fish would have been like scrambled eggs in my tank if that were true. Luckily I had a portable PH/thermometer handy to double check for accuracy. I had to order a completely different thermometer. I don't normally write bad reviews on products, but I wanted to let you know so you don't make the same mistake. If you are looking at a digital thermometer, then I would recommend one made by Coralife. It is small, but works great.
Is the review positive or negative?
