My main reason for getting this IR temperature gun was for checking the surface temperatures in my reptile’s vivarium’s (Bearded Dragon, Corn Snake and Geko) and its perfect for this and by far the most accurate and easy method for making these spot check and when setting up new viv’s. It requires one 9v battery which is included, then simply press the trigger and aim the red laser at the surface that you want to read the temperature of, the reading is “live“ whilst the trigger is pressed so the reading on the display will change as you move the red dot to different areas which is great for checking for hot/cold spots on surfaces, then on realising the trigger the current reading is fixed and shown on the display. There are 3 buttons below the display the first one switches the laser pointer on and off, the second switches the measurement between Celsius and Fahrenheit and the third switches the back light on the display on and off. This is a cheap and accurate way of taking temperature measurements from many surfaces, it has so many uses it would be impossible to list them all. Have to add my cats think it’s a great toy and go mad chasing the laser around!

I bought this so I'd be able to estimate temperature of glue in replacing my phone's broken glass screen. It also turned out to be one of the cooler "toys" I've had in my hands. I wouldn't say it's 100% accurate, but it's accurate enough, and very easy to use with the laser pointer. It has a sturdy feel to it despite being made out of plastic, and the nine volt battery required for operating it fits inside the handle. The screen is easy to read, especially with the background LED on. If I were to use this in a professional capacity, I would probably find the lack of settings (on/off backlight, degrees F or C, laser on/off are the only ones available) and less than perfect accuracy a problem, but as far as hobby projects and "fun" home experiments go, this is a great value buy that I would recommend to anyone.

Having difficulties getting a hot water bottle at just the right temperature, so decided to buy this item. Now the temperature can be checked and adjusted as neccessary without the risk of being too hot or cold. A great addition to my arsenal of equipment. I have often wondered what temperature my freezer runs at, now I can check the temp and be reassured it is performing correctly and my food stuff is safe. I imagine there are many more uses for this piece of equipment, as yet to be found. Highly recommended even for a 'bit of fun gift' for the inqusitive amongs us.

I agree with the previous reviewer - it feels surprisingly well made, for something so inexpensive. Works well and seems accurate to within a degree or so. The fact that it's portable and instant means that, in effect, it can do the job of a number of thermostats. It came without a battery, but at this price, I'm not complaining. Just make sure you have a 9v matchbox-shaped battery at home for when yours arrives. Interesting factoid: the outside temperature of a long-haired cat is about 2º lower than that of a short-haired cat!

I intended to buy a different brand that was double the price, but I'm surprisingly happy with the product. Materials used are good quality and feels pretty sturdy too. Item arrived after 2 days of purchase, absolutely brilliant gadget, and so versatile for baking, tempering chocolate, spinning sugar, temp checks for sauces and holding hot food. I still haven't had the chance to fully utilise it, but I look forward to using it for multiple things in my college course, highly recommed this product.

I got this to measure the temps of Servers and other electronics just as a general idea when the temp sensors aren't working. So far I've measured everything (and everyone) at home and at the office (including our bunny) Some random things I found it is quite accurate on include, water, oil, food, bunnies, people, radiators, lights, car parts, the person who looked at me funny in Tesco, and my Boss. I have yet to use it on a computer. The beeping when it scans is annoying the other half, any way to turn it off?

Bought this Digital Infrared Thermometer as we wanted to see where the draft was coming in our living room. The GM300 Digital Infrared Thermometer arrived very quickly and very well packaged. Its really easy to use, just simply point at an area in your room and press the button on the handle and it will display the temperature in seconds on the screen. The temperature displayed on the screen seems very accurate and the device is fun to play with (I'm a big kid). Overall I'm really happy with this device and could highly recommend to anyone.

I bought this remote thermometer to check the temperature of bath water. I am disabled and have little feeling in my hands and legs which can lead to scalding when I get into a bath of hot water. I picked this thermometer because it is substantial to hold (I drop a lot of things) and I can take the temperature of the bath water from a reasonable distance, negating the possibility of dropping it in the bath. It works well and I am hopeful that I will not suffer any other scalds. I cant vouch for accuracy but for what I want it is more than adequate. It is easy to use for somebody with weak or infirm hands. All round a good buy.

This is an instrument which deserves more popularity as it has so many applications. I don't think people are aware of its potential. The laser pointer beam makes it easy to select the object being measured if it is small. To make a reading all that is needed is to point and quickly press the trigger. The pistol action and the screen on the back are really ergonomic. There is a beep when the reading is ready and the LED lights the screen for a few seconds. One should wait for the light to go out before pressing the trigger again. Three buttons are available to control the laser beam, centigrade/fahrenheit selection and the screen light as well as the trigger, which measures continuously if kept pressed (scan) or almost instantaneously if released quickly, holding the reading for a few seconds. The beeps indicate that the measurement is finished before reading the temperature. Applications are to measure surface temperatures. Liquids such as tea,soup read lower than solids at the same temperature. Wall temperature is generally lower than air temperature if the air is being used to warm the room. The ground temperature is also always lower than air temperature. However, since the readings use very little current from the 9-volt battery in the handle, you soon develop a feeling for establishing the average through several measurements. Ideal for setting up thermostats to economise on heating without freezing, finding cold spots caused by draughts or inadequate insulation, to measure food temperature before serving and during cooking in oven or microwave. In conjunction with a count-down timer makes cooking in micro-wave or re-heating very reliable. Is it cold outside? Just open window, point and read. Brilliant!

Original Comments I've been called cold blooded before but I'm apparently 27.9C with this device when a human body is normally 37C. In fact all temperatures seem to be up to 10C low I need to decide by the end of today whether or not to accept this gross inaccuracy. Update 16 Oct 15 Since receiving a comment from Mike about core body temperature, I've updated the rating to 5* as I believe I was probably wrong with my initial assessment. After further testing I think the device is more accurate than I first thought, and for the price it is excellent value for money. I will not be using it for absolute temperature measurement, but instead I'll be measuring temperature differentials.

This IR Thermometer is a really cool gadget thats genuinely useful. I brew beer. Everything has to be sterilised to avoid unwanted infection. The ability to check the temperature of anything without touching is superb. This gadget would have cost hundreds of pounds 10 years ago and been unaffordable in the domestic environment. Today its a seriously affordable useful kitchen accessory with uses that go well beyond brewing beer. The most useful application is checking the temperature of a liquid being heated in the microwave, without touching.

I am a chef. I worked with a chef recently who had one. While making sugar syrup he used this product and it was actually pretty accurate. So I got myself one and it is very good for a number of thing. However chefs reading this it is no substitute for a probe thermometer as it only gives out surface temperatures. I would recommend this to guys in the trade good for fast delivery checks on vans and fridges. Ovens and at this price amazing. And the delivery was practically next day. Amazing service.

While it worked it was accurate within a couple of degrees / percent as specified. As expected that depends on the emissivity of the surface you are measuring though black tape on a shiny surfaces helps. (My furiously boiling metallic kettle then read 100C.) The unit failed after 6 months and now just says "Err". I am replacing it with a unit with adjustable emissivity settings such as the GM700 or GM900. I was probably unlucky with the failure. If you don't understand emissivity then you will have equal problems with any other IR thermometer. (I disregarded the failure for my star rating)

I bought it for fun and it is fun. I spent a few minutes measuring around the room. I was interested to find that the outside wall was cooler than the others and I found a real use within minutes, the temperature of the top of our Aga which had scorched something left on it. So I am pleased that I have it, although I have nothing planned for it. I offered to measure the outside temperature of a joint my wife was cooking, but usually it is the inside temp you need. Thoroughly recommended, and occasionally essential, but always fun.

Great product and am delighted. Clear easy read screen. The laser can be used to "sight" the target area you are measuring. The manual that accompanies it clearly explains the various factors or parameters that affect all non-contact IR thermometers. My uses are mainly comparative (checking radiators etc) and therefore I have not attempted to calibrate it against a reference but as far as I can see , the readings are within a °C or so . It does the job and is MUCH better than another make that I used to have. Easier to use, clear screen etc.

Good a giving a sense of where cold spots and warm spots are in a room or a house; very helpful in identifying sources of cold or of heat loss. One perhaps lesser concern is that the useful red laser dot/pointer may not be aimed at exactly the spot where the device takes its temperature reading. With the red dot on / aimed at a 15mm warm hot water pipe, I was getting the temperature from the wall behind it rather than from the pipe. The solution was to move the red dot around (maybe 1cm away from the pipe) until the higher temperature came up on the read out. Its still a great device for the price. DMK

For a simple point and click optical IR thermometer this can be surprisingly accurate, but only if you follow the sound advice given in the instruction sheet and use it intelligently. It can be used to take a spot reading centred on (or near to) the place indicated by the laser pointer and this is held on the display for seven seconds after releasing the trigger, or it can be used to sweep across a surface while holding the trigger and show the continuous variation in temperature. It has three buttons; to toggle between °C and °F, to turn on/off the display back-light, and to turn on/off the laser. The last two options produce a worthwhile power saving doubling the battery life, if one knows where the device is aimed and has enough ambient light to see the display. Distance is significant, and being closer to the object in question increases the accuracy by choosing a smaller spot. However, it seems to work well at quite long ranges too, provided the target is big enough.

This thermometer is excellent for measuring temperatures of surfaces that are otherwise hard to determine. Simple and easy to use I have been using it to find cold spots around the house to improve the insulation. The back-light display is very useful in dark places, but the laser-aim seems of limited value given the 12:1 spread of the beam with distance. The only slight down sides are that (i) it doesn't work on shiny metal surfaces (readings far too low). (ii) the accuracy is specified as +/- 1.5 C. As far as I can tell mine is under-reading by about 1 deg C. These limitations may not matter to you and may be 4* is a little harsh. Overall though I am very please with what I got for my money.

I have recently built a wood-fired bread oven. It is one of those ones that you sometimes sGM550ee in Pizza Express. The outside of the oven is covered in a ceramic fibre blanket which should allow it to get up to temperature and stay there. The problem is to know what is going on in the oven and whether there are local hot spots or cold spots. The GM550 is brilliant for this. You can instantly find out what temperature the walls and the base are at. It even has back light for use in the dark. The laser gives you a good guide of the location where you are measuring the temperature; although you do need to compensate for distance (there is a guide printed on the side of the unit). Highly recommended.

I'm sure im not the only one whose first job with this was to go around the house 'shooting' the walls / windows / bath / fish tank / kettle to test their temperatures?! I expected this to be a bit cheap and nasty but it is really nice in the hand with soft rubbery coating on the plastic. Supremely easy to use (once you get a 9v battery) - just point and shoot. The laser pointer is useful so you know you're testing the right thing. Seems fairly accurate. Only bought really to muck about with and check for cold spots in the house. Only thing i would say is that it would be nice to have a bag or some sort of case or even a hanging loop as it is liable to get damaged chucked in a drawer / shelf somewhere.
