Super simple. Attach a suction cup to the windshield (or wherever you need the thermometer) and hang the thermometer. Insert probe. Attach the probe to the glass. Did. Is working. Press the button on the front and read the temperature. Press the button for three seconds and it will turn off. You can not ask for more. Does it look a little cheap? Yes, but I forgive it because it works great. No more searching through the aquarium looking for a floating glass thermometer! It's also much easier to read than glass or stick-on thermometers.
