Accurate for cooking January 1, 2009
I use the unit in the making of high heat confections. Modern microwave units do not have a high temperature sensor (300 degree) making accurate and predictable results unreliable. To get accurate readings from the unit, I remove the pyrex container from the microwave, point the Extech at the center of the mixture and know the exact temperature instantly. It is a good little unit that delivers on accuracy and convenience.
Useful instrument at a bargain pricetag September 22, 2007

I bought this for an arcane research application (for which it was fine), but found it was also useful around the house. As we'd had trouble with A/C units and airflow in the vent system, I used this IR thermometer to check the outflow temperature and the wall temperatures around the rooms. It's easily precise enough for such uses, and other reviewers have already mentioned other home uses.
Great for the home January 3, 2007

The Output A/C temperature should be about 59 degrees (cooling) and 100+ for a Heat Pump or 120+ degrees for gas heat at the Ventilation Register. Keeping track of your own system's performance saves on calling the Repairman needlessly.
Measure the temperature inside your refrigerator to make sure it is cooling sufficiently and the freezer, too. If it's too high, save money by vacuuming the coils on the back or underside yourself to avoid component failure, again saving money on Service Calls.
Check the accuracy of your Heat and A/C Thermostat. If it is off, utility bills can escalate.
Great little investment that we use frequently.
 fun to play with January 3, 2007

Haven't found it's true potential, but It defines hot spots in the oven, and cold spots in the refrigerator and if the double pane windows are working or not.
