I always thought these were way more expensive. Then I needed to know if a wet patch of drywall was active or dry, and I know using one of these is a way to figure that out. This was very easy to use. It was fun learning about how different sections of my condo are a couple degrees warmer or cooler depending on external -vs- internal walls, proximity to AC supply vents, return vents, etc. Never knew the surface of a car was so hot - e.g. the actual temperature.

I had the cheap knock offs bearing different names albeit having the same inside components. I also have the Fluke 62 Max. Some of the knock offs now are only about 30% cheaper than this Klein. Fluke is at least 30% more expensive with even less features.

This unit has the perfect balance among features, durability, accuracy, and price - dual laser, 12:1, min-max-ave-diff, and easy to set and use. Just point and shoot.

The only feature that is less than the others is it can only go 752F (400C) max. But since I will only use it mainly to monitor the house, car, oven, and grill that maxes out at 600F for searing, this unit is good enough for the range.

I purchased this tool expecting that taking a temperature reading of copper heating pipe would be as simple as "point and shoot".

Turns out it's not so simple: in short, materials have different levels of "emissivity", and the thermometer needs to be set accordingly per the materials emissivity table included in the manual.

This ends up being more complex than it sounds, especially with metal surfaces. It's sometimes hard to discern exactly what the material is (e.g., is this iron or steel? is it oxidized or galvanized?), and some materials have such low emissivity (copper) the readings don't seem reliable..

A workaround is to apply a coupon with a known high emissivity (like 3M Super 33 electrical tape), allow that to come to temperature, and read the tape. This works fine for many applications.

Anyhow, just read up about emissivity and think about your applications before you decide to buy.

Works good. I'm a HVAC technician and a tool nut I have a Milwaukee a UEI and the Klein. And many times Ive used them side by side to assure no drastic differences in temperatures and the Klein holds up well. No need to spend over a hundred bucks on one to get perfectly accurate readings, the Klein does just fine.. I recommend this or any Klein tools to anyone looking for good and reliable products in the field

I three-level home during the winter season. I have to adjust the temperature to try to get the level warm. Without sweating on one level. Or wearing extra clothing on another floor. It has been truly amazing using the IR5 tool. Very simple to use, easy to carry, just point. The direction is very simple to read comprehend. I have been able to maintain a constant temperature on each level of my home. I saw a drop in the electric bill.
