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 eggsGreat for OC temp Monitoring

Pros: -Works with Fahrenheit and Celsius
-very accurate
-affordable
-Digital
-Infrared

Cons: Non so far

Other Thoughts: I love having this laying around to verify live thermal temps during overclocking and can help verify if any on-board sensors may be off or inaccurte AND CAN SAVE YOU TIME AND MONEY BY CHECKING SENSORS TO SEE IF IT IS BAD AND NOT A BAD VRM OR HEATSINK ETC.

5 out of 5 eggsMy dad loves it

Pros: Great Price and it works just fine.

Cons: None

Other Thoughts: Bought this as a gift for my retired Dad and he's having a lot of fun checking out the temps of everything.

5 out of 5 eggsVery useful

Pros: Got this on sale and it comes in really handy. Operation is simple - just one button to press. I don't use it frequently but I've had it for 10 months and still have the original batteries in it, for whatever that's worth.

Cons: Laser is not lined up with where the actual measurement is being taken, but it's close enough to be helpful.

Other Thoughts: I have no way to test the accuracy, but it seems right to me. If nothing else, it can point out a temperature difference.

5 out of 5 eggsFun and Informative

Pros: It was on sale. Got it and now I know the temp of everything. Kinda neat to use around the house....find out if you have insulation problems....see what your motherboard's actual temp. Seems somewhat accurate with the laser.

Cons: You have to play with it to find where the laser and the measurements actually take place. Mine is about 1/2" low at 8". Once you know this, it will make it a lot more sense.

5 out of 5 eggsMine has worked well for 2+ years

Pros: Great value when on sale. HOWEVER, contrary to what some purchasers seem to think, it is NOT meant for measuring body temperatures. Well, that is, if you expect it to read 98.6 degrees on your hand because your hand is rarely that temperature!

My thermometer has allowed me to do the following: Locate overheated and damaged wiring inside a wall after a lightning strike, identify the cause of an overheated circuit breaker, verify a defective fan motor, check the operation of refrigerators and air conditioners, compare wall and ceiling temperatures before and after insulation was installed, identify defective components, etc, etc. Once you have one and get into the proper mindset regarding its utility, you will discover more and more ways to use it.

Cons: It's not free and, even though it doesn't use the dreaded 9 volt batteries, it does use AAA batteries. AA would be better. But, because the batteries have lasted more than two years, I suppose the AAA batteries are OK.

Other Thoughts: Look, this product has more than 350 reviews. Currently, 7.56 percent of them are LESS than FOUR stars. That might be a record. When I look at reviews, I generally try to find items where the 4 and 5 star reviews combined are at least 75% of the total number. Obviously, 92.44% is far above that threshold! The 5 star reviews amount to 76% by themselves. That doesn't mean you won't get a bad unit. But, it does mean the good units are just that - Good.

I am not telling you they are certifiable by the National Bureau of Standards. But, they are plenty accurate for everyday use especially when comparing before and after or normal versus abnormal. Most of the measurements I make fall into those categories. Rarely do I need to know if something is 115 degrees as opposed to 120 degrees. BUT, when I do, I can simply heat (or cool) some water, etc to the desired temperature and compare this thermometer's reading to that of a trusted thermometer. That way, if the Rosewill is off by 5 degrees, I can adjust the reading accordingly.

At 16 bucks, on sale, it's hard to go wrong.

5 out of 5 eggsGood Thermometer

Pros: Very accurate. Matches thermostat and GPU temp readings. Comes with Batteries. Study, good price. Reads both *C & *F

Cons: Not really a con, but when item was listed, didn't specify if batteries were included -which they're included.

Other Thoughts: I got this mainly to measure VRM temps on Gigabyte GTX 780 OC Windforce. GPU idle is about 32*C, VRM temps 37*C. I find this very useful for my indoor greenhouse -some seeds requiring specific germination temperatures.

I'm very satisfied with price and quality
