Remark:

Emissivity: Most (90% of typical applications) organic materials and painted or oxidized surface have an emissivity of 0.95 (pre-set in the unit). Incaccurate readings will result from measuring shiny of polished metal surfaces. To compensate, cove the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface.

5 out of 5 eggsWorks Very Well

Pros: Fast response time. Accurate, or at least consistent temperatures. Very impressive range. Uses cheap AAA batteries.

Cons: Would have like better than .5 Deg F readout, but this was in the specs.

Other Thoughts: It worked great out of the box. I quickly started having fun going all over the house looking for hot and cold spots.
It appeared quite accurate and consistent, but only with the stated .5 degree increments.
I was most impressed with the range.
I could get an accurate reading from as much as 20 ft away. Most reviews say that these guns are only accurate at close range so I was very surprised when I got a very different reading pointed at a distant wall only to get closer and find out that the reading was accurate.

1 out of 5 eggsNever been even close

Pros: Sturdy, easy to replace batteries

Cons: From day one temps were a BIT off but not too bad. Over time the meter became less and less reliable. Now 13 months after purchase it says my hand is 93 degrees F. It says that a motherboard that is running hot enough to burn flesh is 93.5 degrees F. 20 bucks wasn't a bad price for something that kind of worked but now its just a laser pointer.

Other Thoughts: Probably buying a more expensive one soon.

5 out of 5 eggsWorks Great

Pros: This infrared thermometer works really well. I tested its accuracy with other thermometers and it is always within a couple of degrees (expected with infrared).

Cons: The screen. You have to hold the unit at an upwards angle to see the screen well.

Other Thoughts: - Is accurate even at a reasonable distance.
- Basic

5 out of 5 eggs

Pros: Works as it's supposed to. It's a useful tool and a fun toy all in one, for a great price.

Cons: You have to be pretty close to the object you're measuring. The 8:1 "spot" spreads out quickly the further you are from it.

Other Thoughts: It would be neat if instead of a dot, the laser could draw a circle or something to show the actual area it's measuring.

5 out of 5 eggsGreat Laser Thermometer

Pros: Inexpensive, well built, accurate, can be used from 50' with dead on results.

Cons: None

Other Thoughts: I originally purchased this to tell me the temperature in my computer case. Since then I have used it to tell me surface temperature of my vents, basement walls, and many other items. The item works great and is accurate as specified. For the price and performance you should buy it.
