Review on Tru Temp Refrigerator Freezer Thermometer Pack Kitchen & Dining by Katie Morgan

Some of them seem badly calibrated but mine was. I received three packs and they all read the same so I'm happy to camp. Cost-wise, they're worth the money even if they're off a few degrees - you can't expect cheap thermometers like these to look like electronic scientific thermometers for $100 or more. It's good to make sure your fridges are running at the right temperature, and that's about it. So for the money they are worth it.
