If you need the best accuracy, spend the extra money and buy a Fluke 62 Max (best one). Of all the units that I have calibrated (I work in a cal lab), this has one of the worst accuracies and repeatability results of any other (±9°F / ±5°C against an accurate standard at 12" away). I suppose you get what you pay for. There are many other models out there that cost about the same as this one that have better specs. I recommend looking up the manufacturer's specs before purchasing any IR temp gun that you are considering.

Rated 2.0 out of 5.0 by dan27 harbor freight model is half the price works better than this
At first appeared to be a good buy. pointing heater vent it appears to be doing it's job but that's all it does well. It is very inconsistent I got a range of +- 10℉ on my hot water pipes every time I test same with the Windows I can test the same spot over and over agian and it's a different reading everytime. Has to be held at exactly 8in if it's even a 1/4 inch closer or farther it reads incorrectly and I believe that's why it's so inconsistent, the margin of error is far to small for the human eye. Works better if u tape a pencal to it and cut it to 8 inches so you can log consistent data at an 8 inch gap

Rated 2.0 out of 5.0 by DesertDude Did not cut it for me.
The first disappointment I encountered was the difficulty of placing the battery in the unit. Very tight fit.
So, as most people will probably do, I started taking the temperature of everything. First, all seemed good as it was close range and in the house. When I went outside though, I noticed the laser was "left of center". The farther away the object - like siding or eaves of the roof - the more noticeable the issue was.
Then, I wanted to get a before and after sunset ( I didn't think of this when purchasing it ) and that was the last straw. No back light.

I am trying to work out some temperature issues in a small room (either too hot or too cold). This product is not down to the degree accurate, but pretty close and gave me a clear indication of where my problem was (the windows). Worked well on AC vents, windows, and walls. It agreed with other thermometers that I am using.
I should have bought this BEFORE I started cutting holes in the ceiling.
Very handy to have.

Fairly accurate readings help identify problem spots. Measured against indicated temps on home thermostats and either matched or off by 1 or 2 degrees. Most accurate when reading temps within a few feet, but still gives fairly accurate readings when aimed 15 or so feet away.

Rated 3.0 out of 5.0 by PeterD Useful but temperature readout not very accurate.
The manual says accuracy is +/- 5 degrees Celsius which is 9 degrees Fahrenheit. At room temperatures the unit I have reads much lower than anything else. At higher temps (food from microwave, hot coffee) it seems to be closer to actual. No ability to calibrate; however it is relatively inexpensive and I have found it useful in locating room cold spots. The accuracy thing doesn't really affect its use for this because I'm looking for differences in temperatures rather than a perfect temperature reading. If one reading is 5 degrees different from another I believe the tool even if, in my case, the readings are both 10 degrees too low. Would recommend if there was a way to calibrate the readout for the range being read but feature not provided.

Rated 1.0 out of 5.0 by CONSUMER HOW IN THE WORLD DO YOU USE THIS THING? WHAT A PIECE OF JUNK!
i KEEP THINKING I'M DOING SOMETHING WRONG BECAUSE EVERY TIME I PULL THE TRIGGER AND POINT AT THE SAME LOCATION, I GET A READING 15 TO 20 DEGREES FROM THE FIRST. AFTER READING OTHER REVIEWS, I SEE IT REALLY ISN'T ME AT ALL. THIS PRODUCT IS A PIECE ON JUNK!

Rated 4.0 out of 5.0 by thereg Works very well but product is now differnet than picture.
I bought this to help determine where I may be close to a frozen baseboard pipe under the floor or behind the wall. The product must have changed in overall design. The current picture shows a blue gun. But at my local Home Depot there are newer green and gray one. There were blue ones on the hager rods but they were 6 or more deep behind the greens. That said this green version seems to be pretty spot on. Matched the tempurature on my thermostat reading. It also gives consistant readings in the same general areas of my tile flooring and heating duct work, concrete foundation. However I am not too sure that ice cubes in my freezer are -15 degrees F. Overall I am happy with my purchase.
