There are all sorts of infrared thermometers out there, of all shapes and sizes. I love this Supco PIT1 Pocket Infrared Thermometer because it can easily be tossed in a pocketbook or pocket. It's that small and easy to carry around. There are all sorts of times that it's good to know what the temperature of something is. A forehead. The air. The dashboard of a car. And wine! Wine is one of those things that can taste delicious at a reasonable temperature and atrocious at a wildly off temperature. This device lets you know if you need to warm it up a bit or cool it down.
Most of the time you just point this at something, press the button, and you get a readout of the temperature. That's how I tend to use it. I dock one star because the button wears down quickly and then you have to press it a few times to get a reading. Still, it does still work, and I've had mine for quite a while.
There are also modes where it will show you the minimum or maximum temperature reached, which are good if you're trying to make sure an area stays within a certain range.
Well recommended for its main purpose which is just pointing it at something and knowing the temperature. I use this fairly often. You'll be surprised in how many different situations it's nice to know the temperature of something.
