This IR thermometer seems to use similar modules as more expensive brands. It could be a copy or an OEM version of many branded models, its commonly listed as the DT-380 or DT8380 Infrared Thermometer. For $12, its a steal if you know more about how to work it properly, and it works wonderfully.
Digital Thermometer 8:1 distance:spot ratio for 380C decodes the model number.
I tracked a similar looking manual and nearly identical device to a Chinese factory, See comments.
The manual is nearly identical to the model I received. I can't disassemble the unit to check the PCB and makers mark since part of the unit is glued.
IR thermometers are calibrated against dark or black bodies, and perform worst with reflective surfaces like stainless steel, foil, or mirrors. For best results, point to dark to black surfaces.
I tested it as no worse than 10F off, at best 1F, when measuring dark to black bodies, respectively. Its rubber coating makes an easy grip. The trigger has a sharp click, its not soft and gummy. The LCD is easy to see, and the best angle for viewing its LCD is also the best angle for measuring, perpendicular to the measured surface. Beware that when the measured point is fairly close and localized, regional changes in irregular or curves surfaces can happen, like pottery, cups, and mugs.
Using a black mug and pot, I checked IR readings against 32F ice water and 212F boiling water. The temperature was compared against an Agilent thermocouple. The IR reading was 0.5-2F off from the immersed probe. IR reads of a hot Calrod heater was compared against a thermocouple to 900F+, and the IR thermometer read true, far above its rated temperature. It read body temperature 0-2F off compared to a standard oral thermometer!
At extremes changes of ambient temperature, the focusing lens need to acclimatize, the manual recommends 30 minutes. For example, if taken out to a hot summer day of 100F, from 70F air conditioning, the unit may read low. Likewise, from a warm car to the outdoors during winter. This low cost unit uses a Fresnel plastic lens which is prone to thermal deformation more than other lens materials. How much the error is depends on the extent of the difference between one ambient temp and another: if used too soon the IR light may not be optimally focused onto the IR detector.
I am impressed, so I bought another! I've been looking for a good deal on these for years, even Harbor Freight can't match it.
With 2 units now to compare I tested acclimatization, I took one unit to a 73F cold airconditioned room and left one out doors at 85F for 1 hour. Sure, enough, they were off ~3F when they were reading nearly identical earlier. After 1 hour with both units in the same room, they were off from 0-0.5F, awesome!

After looking at various infrared temperature guns I wondered what I would be missing by settling on this less expensive model. As it turns out, this product does everything I need and more.
The laser sight can be switched on or off, and the temperature gauge can be switched between Celsius and Fahrenheit. The unit operates on a 9-volt battery which was included in the package.
Temperature readings are quick and perfectly accurate. The display is bright and plenty large.
I use this to read the surface temperature of my pans when cooking on the stove, which really helps create consistent food quality and delicious meals.
I've also used it to locate potential thermal leaks around outlets on exterior walls.
The only potential downside to this product is the limited temperature range (other models offer a larger range), but frankly, I can't think of any reason why I would ever need to read temperatures higher than the capability of this unit.
Simple, easy to use, and relatively cheap. Nothing to complain about.

I purchased this thermometer and tested it when I received it. Worked fine, seemed to be pretty accurate. I then put it in a drawer until I needed it again. About about a month, I retrieved said device and it would not turn on. The battery tested good and I tried a brand new battery in it. Still no luck.
I contacted HDE about this issue and this is their response:
"Hello,
Thank you for contacting HDE. Unfortunately our return policy is the only warranty for this item. Unfortunately we will not be able to assist with a replacement/refund.
Thank you
HDE"
So, now I have a paperweight that used to take temperatures. You may be luckier than I. Caveat emptor.

Didn't Work
I waited too long to send this lemon back. Barely worked only a blank screen then not at all. At first I thought maybe it was the batteries but that wasn't the case.

Works in F or C.
This is a good, inexpensive unit that does the trick for your needs. There is a switch inside that lets you go from C to F.

Dead within a year
Worked well for a few months, then stopped. I assumed the 9-volt died and waited a few months to try it again with a fresh battery. New battery and it still doesn't turn on. Read more

5.0 out of 5 stars Great Thermometer,
Easy to use. Only con is it doesn't go above 750 degrees F accurately. I use this for a pizza oven and it does the trick very well. Seems to be accurate within 4-5 degrees. Read more

Very handy tool
Very inexpensive, works great. I've used it to measure heat loss in our home and manage the temperature when roasting on our wood-fired grill.
