I used it few times and these are my observations: Pros: 1. comfortable and easy to use 2. cheap 3. Like the feature of continues monitoring when holding the button 4. Laser pointer for the targeting 5. Good packaging and quick delivery Cons: 1. not always accurate, the reading can be affected by the color of the material it is made of In general good for a rough orientation. Worth the money but if you are looking for something more precise you should get ready to pay more than 7 times more (flir or fluke)

This thermometer has done the job I bought it for, to find cold spots in our house. I searched our house for draughts prior to getting this item without success but within a few minutes using the GM550 I had identified several cold spots. This thermometer seems to be fairly accurate around room temp. but below freezing point it is a long way out. I took it outside on a frosty morning when my out door thermometer was at -1.2 C. and I was getting readings around -13 C. As the product description says (Measurement Range: Between -50 °C and 550 °C) but (Operating Temperature: Between 0°C and 40°C) maybe the unit would not be accurate as the operating temp was below freezing. I then went to the deep freeze opened the lid and aimed the device in the freezer, I got readings between -35 C and -37 C. When I took items from the freezer and tested them I got reading from -30 to -35 C. I have tested temp in deep freeze and it is showing -18.7 C. I have not had the opportunity to test at high temp yet but did test on boiling kettle aand got reading of 60 C but as this is a polished surface I did not expect an accurate result. So beware of accuracy of this item.

I've cooked my best fish and chips ever thanks to this, OK and some nifty home made batter and great maris piper spuds, but getting the oil at the right temps was crucial and this baby sure helped me there, and the wife's belly came in at a cool 35.4c too, and the fridge was a good 4c too, and the radiaters were giving off 20c , and heck you get the idea, it does what it says on the box/advert/tin perfectly. Unless i need another to check its not lying, but those chips were so good I don't think it was! Wish I had a cat to annoy with the laser....

I tried this straight away on receiving since I was curious to see how useful such a low-cost unit could be. On first use, it persistantly measured about 5 decrees C too low. I was preparing to send it back but gave it another go an hour or so later. It was spot on! (No pun intended). Making allowances for the different surfaces on the things being measured, I found it to be very accurate. I have a number of electronic temperature guages around the house and found it to give the same reading (disregarding the odd fraction of a degree).. Surpridingly, it gave the axact same temperature inside my fridge/ freezer as was set and displayed on the front panel. I was impressed. I have used on people just for fun and the results have been interesting. For example, it's a great way of taking the temperature of the grandkids when you think they might be under the weather.

I'm really impressed with this thermometer. Its amazing how technology has progressed. For less than a tenner, I now have a device that not only gives an instant temperature reading of any object from a distance, but also includes a built in laser pointer to show you exactly what you are pointing at. We tested it calibration by using a conventional thermometer in a cup of coffee, then comparing the reading to this infrared alternative and it was spot on. It couldn't be easier to use either, just pull the trigger and wait for the bleep (2 seconds max) and it displays the reading. We have been using it to find the source of a cold draught in our ancient kitchen - just keep the trigger pulled and sweep the device around the room, and when it encounters a sudden change in temperature it beeps. Brilliant - let's hope it lasts!

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!

You are not going to use this every day, but then that's true for most of us who have soldering irons, but I can see there are times where it will be so useful to have this in the tool kit for checking temperatures generally and differences. The unit is dead easy to use, proved accurate and immediately identified a radiator coming up for bleeding. Was surprised at the cold spots on my front door and the heat leakage pattern through my walls. Using it on electrics such as trailing leads and plugs was also very informative! Get one.

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!

Despite being relatively inexpensive, this thermometer is actually pretty accurate. I measured steam coming from a boiling kettle peaking at 99.0 degrees C. That's only a 1% level of error. Certainly accurate enough for anything I'll be using it for. You can enable or disable the laser pointer as necessary, as you can the backlight on the display. Pulling the trigger enables the 'measure' mode and provides a constantly updating temperature reading. Releasing the trigger 'holds' the reading for around 6 seconds so you can read it off. It then automatically powers off, preserving the battery life. A great little gadget I wouldn't like to be without, especially at this price.

I bought this to measure the temp of several aquariums - it's great, instant reading when pointed at the tank, then move on to the next. Bright clear backlit screen for results, takes a regular 9v square battery which is supplied. Obviously I spent the first few days measuring the temperature of everything from my dog, oven, tea, the sun (results inconclusive on that one - possibly slightly out side the usable range) as well as winding the cat up with the laser pointer. So to sum up, it's a thermometer which functions very accurately and quickly, looks like a gun and has a laser on it. Obviously everyone needs one of these in their life.

Surprisingly accurate. A friend checked the measurements provided by the GM550 against his premium FLIR model and, over a course of five readings, the 450 degrees C temperature was measured accurately within 20 degrees. The GM550 is however *very* sensitive to the black body quality of the object being measured. The burned bits on my pizza oven give a spookily accurate reading but the "clean" bits aren't even in the correct ballpark. This isn't a criticism though because for this price the GM550 is a great buy with an accurate beam. As long as you understand the basic concept of black body radiation - how IR thermometers work - you won't have much to complain about. For occasional use and if you can't justify the price of a premium model this, I think, is the one to get.

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?

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.

It is always a bit of a punt buying something like this sight unseen, but I wanted a quick method of working out heat loss on heating installations and took a gamble. The heat range on this device is -50 to +550, so more than adequate to meet my meagre needs. Very easy to use, just aim and pull the trigger and the temp is displayed on the back. I'm pretty fortunate that where I work they have a very expensive and calibrated heat sensor that cost about £4k ... within the range I am interested in, i.e. 0 - 80C this cheapy unit worked within about 1% accuracy ... certainly good enough for me, and they are going to let us lose with the expensive kit.

Taking temperature of fridges / freezers and display units for health and safety forms is so quick with this. Also if you turn off the laser is becomes a baby forehead thermometer £50 usually. It has also been used to see if something is too hot to handle a few times, see where hot spots are in the ovens. See which oven is hottest and find out exact temps in locations so they can be replicated elsewhere for consistent cooking. I have also mesured the babies bathwater with this. Soo useful. Gives same temps as a more expensive probe but quicker. Can only measure surface temp so a probe will still be needed. For everything else there is this

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.

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.

Extremely versatile, fairly accurate* and easy to use. Warning: You will be tempted to measure the temperature of everything: - My cat, soaking up the sun while taking a nap, can reach a surprising 65 C. - The perfect temperature for a Raclette is 105 / 108 C. To try at home: Point at the sun, and take a reading. Point at the opposite direction (sky) and take a reading. Ask your kids to explain that ... Use a mirror and take a reading at different things pointing the IR Thermometer towards the mirror. Ask your kids to explain that ... I like: Easy to read, has both Celsius and Fahrenheit Back lit screen on/off and laser on/off button With the laser on, you have a fantastic cat toy! Good hand grip With the laser on, you have a fantastic cat toy! Battery included With the laser on, you have a fantastic cat toy! Did I mention the laser cat toy? I dislike: The beep-beep It would have been nice to have been able to turn off that noise. It's fine the first 3 time, but after a while, it's getting old. The cat agrees. The wife too. *Accuracy: Don't ever forget that it is measuring infrared (reflecting from a surface, partially or not i.e glass) and that is has a cone shaped measurement range. The closer the better.

I never ever thought for one minute that this would be of such good quality and, I believe accuracy. I have been a surveyor for many years in the past and now live in a nice one bedroomed flat, but it gets MUCH too cold in the Winter, and unbearably hot in the Summer. I have only used it for the first time, and all of my expected temperatures were as expected. I have shon it on my several walls, ceiling, floor, my leg and TV - both on standby and on. It has confirmed my fears that my old pvcu (12mm air gap) are to largely blame. So, now that this has been established I am going to buy secondary glazing, because my housing society will not pay for ne, and wider air gap new double glazed windows, and with low emmisivity glass. What a product for the price, all of the different temperatures were confirmed more or less as I expected. Five stars definitely!
