The Raytek MT4 Mini Temp Non-Contact Thermometer Gun with Laser Sighting is the handiest infrared thermometer we have found. After trying several other brands over the past few years, we have found the Raytek to provide results closest to insertion thermometers. We primarily use three of these in our candle making business, but also have two for around the house and in the kitchen (including a Mini Temp Non Contact Thermometer Gun (RAYMT2)). Here are my observations:

* Easy to use and aim with laser targeting (literally point and click)
* Solid design takes a good bit abuse
* Very accurate but takes surface temperature, so liquids should be stirred before reading

Highly recommended!

I got one of these for Christmas two years ago. At first it was just a fun toy. Then I realized out how useful it could be. I diagnosed a sticking brake caliper by checking the temp of my rotors. We used it to set the thermostat in the freezer. I now know my oven is off by about 25°. I know the hot spots on my BBQ. We check the temp in the hot tub to see if it's warm enough yet. It gets used much more than I thought it would. BTW. It's still a fun toy. Our cat chases the laser everywhere.

I love the Raytek MT4. It is quite accurate and good for any number of household jobs. Both my wife and I use it in the kitchen for everything from checking the oven to the refrigerator. I even use it to check on when I need to clean the fan on my laptop computer. The grand kids love it too but need to be supervised so that they will not shine the laser bean in each others eyes. We even took it on a vacation trip to Yellowstone NP where it was a big hit. We have given one as a Christmas gift to all our family members and all have reported great new uses from checking the wood stove to the heated seats in cars. Buy it and you will wonder how you did without it.

My late wife gave me one of these many years ago, when it was an industrial tool and cost three times as much. It is still working, and I have used it daily. It is currently my favorite gift for most any special occasion. Though the laser in mine has become unpredictably intermittent, it hasn't affected its accuracy, and it works on griddles for pancakes, cups of water in the microwave, bread dough, walls, floors, ducts, most anysurface up to 500ªF, and the new ones seem to go to 750ºF. No kitchen should be without one.

When you make truffles, the chocolate must be heated to just the right temp, and at certain temps, you will ruin it if the chocolate is stirred. Having this type of thermometer works like a charm!!

I have bought two of these - one for home and one for work. I bought the first one to check out a malfunctioning HVAC system in my house, but soon found other uses or it, like checking my refrigerator/freezer, the temp inside my car, etc. I got another one for work for similar issues.

Everyone has fun pointing it at everything to see its temp. But mainly, the device is super simple to use, the battery lasts forever, it's durable - and fun!

I definitely recommend it.

We use it for checking room, equipment motor, and cooking temperatures. It's quick, easy and accurate. A friend of mine is a building manager and he has had one for a couple of years and relies on it daily.

I have an old house and recently installed a pellet stove. I've been curious as to how hot the stove gets and also wondered if there were any major holes in my house letting the heated air leak out. I looked into buying one of those heat sensing cameras but discovered they cost a fortune and then came upon this little thermometer and am impressed with it's accuracy and cost. According to the MT4, my stove puts out air measuring about 240 degrees F and I haven't found any spots in/outside my house that are leaking heat. Also, I learned I needed to make my frig a little colder, that my hot tub really is 104 degrees F, that "5" on my electric stove is about 350 degrees, that my dog is always 80 degrees, that sweat on my forehead keeps my skin temp at 85 degrees but when the sweat dries, my skin temp rises to about 95 degrees, my heated car seats get up to about 105 degrees - no wonder I always turn them off after a few minutes. Lots of fun and uses. I think everyone should have one. Accuracy was tested by measuring the wall temperatures next to where I hang old style mercury thermometers throughout the house and the readings are always (+/-) 2 degrees which is within the published margin of error.
