This works fast. I have used it many times in different workplaces and it always works. Very light to carry. I love the color as it matches with all my other nursing supplies. It is durable and I love the auto shut off function when not in use.

Works great for my patients

Nice product

I bought this infrared thermometer as part of a deal with a Pulse Oximeter. I also bought another brand of infrared thermometer. They do not read the same on the same forehead at the same time. Also, neither works in a cold environment, kind of useless due to this. I'll be getting a good old fashion glass thermometer that always works. I do like the GG infrared thermometer's ability to be used to measure other surfaces besides foreheads.

Great

It just works. That’s what we need and it’s great to be able to trust a brand and know when we pick their products, that they will just simply work. No hassle. No need to buy other items like batteries or case because it already comes with them. Clear directions on how to immediately start using the product. All the little pitfalls of other products are thought about and handled with simple clear design.It tells you when you are close enough to the person so that when taking someone else’s temp, you have a visual to confirm you got it right.It is also instant read with an audible beep, so if you are taking your own temperature and obviously then can’t follow the visual prompts to move closer, your just move it closer until it reads and makes the beep sound, and you know you still got it right because with instant read, it reads and beeps as soon as it is where it needs to be.You can turn the beep on or off. And you can measure the temp of a person or an object. It has a button to toggle between human temp with beep, human temp without beep, object temp without beep, and object temp with beep.In the human modes the screen will also backlight red if the temp is above the standard fever threshhold.

Overall Rating: 3/5Accuracy: 3/5Installation/setup easiness: 4/5Ease of Use: 5/5Build quality: 4/5Utility: 4/5Illumination Brightness: 4/5Illumination Utility: 5/5Hereinbelow is everything you NEVER wanted to know (BUT should know) about Infrared (IR) Thermometers (including this AVERAGE one from Greater Goods).In order to be able to trust that a FEVER thermometer’s READING of 96F is really a TEMPERATURE of 96F and that a FEVER thermometer’s READING of 106F is really a TEMPERATURE of 106F, the most important attributes for ANY kind of FEVER thermometer are its temperature-response’s linearity, precision (viz., its repeatability/reproducibility), and accuracy (viz., how close its READING is to the REAL, actual core body TEMPERATURE).Fortunately, based on my own DIY thermometer-calibration test method (detailed below) which I use to test the TEMPERATURE response of any fever thermometer I buy, the TEMPERATURE response of this Greater Goods Infrared (IR) Thermometer DOES reveal whether or not one has a fever.-- BUT, unfortunately, its temperature READING seems to be always LARGER than the REAL temperature.Consequently, I use this Greater Goods Infrared Thermometer ONLY as a screening tool, but I don’t trust it for a FEVER measurement; instead, I use a regular thermometer (electronic or mercury or alcohol) to definitively determine the REAL, actual core body TEMPERATURE.Notwithstanding, this Greater Goods Infrared Thermometer serves my needs ONLY as a FEVER-screening tool (I then confirm whether or not any of my Loved ones has a fever by using a regular thermometer).FYI: This Greater Goods Digital Infrared Thermometer apparently is set for an EMISSIVITY >0.98 (discussed below) in BOTH the OBJECT mode & the HUMAN mode.QUESTION: Does anyone else make/sell an ACCURATE and PRECISE Infrared FEVER Thermometer?-- I don’t know, but based on the technology (detailed below) which undergirds all Infrared Thermometers, such an ACCURATE and PRECISE Infrared FEVER Thermometer might be miraculous and/or very expensive.===========TECHNICAL BASIS OF ALL IR THERMOMETERS===========According to en(dot)wikipedia(dot)org/wiki/Infrared_thermometer“An infrared (IR) thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured.”“…readings may be subject to error due to the reflection of radiation from a hotter body—even the person holding the instrument — rather than radiated by the object being measured, and to an incorrectly assumed emissivity.”“Simpler instruments may have a measurement error of about ±2 °C or ±4 °F.”According to the Stefan–Boltzmann law, radiant power is proportional to the fourth power of temperature, so when the measurement surface has both hot and cold areas, the indicated temperature may be higher than the actual average temperature, and closer to fourth-power mean average.“Most surfaces have high emissivity (over 0.9 for most biological surfaces) and most IR thermometers rely on this simplifying assumption; however, reflective surfaces have lower emissivity than non-reflective surfaces.”MUST READ: tinyurl(dot)com/2p9xr933 (BEST-PRACTICE GUIDE for the USE OF INFRARED FOREHEAD THERMOMETERS)“…clinical studies (in which measurements were compared with core temperature references) do not support the use of forehead thermometers in a clinical setting for identifying febrile individuals and IRFTs’ ability to measure body temperature was, in general, considered to be outside the clinically acceptable limits.”“…the emissivity of a surface is the ratio of the radiation emitted from this surface to the radiation emitted from a blackbody at the same temperature. In the case of IRFTs, the emissivity of the skin can be considered to be between 0.94 and 0.99, so the thermometers should be adjusted for this emissivity.”“…Nine thermometers (three types) were measured and compared with national standards and the results show that at least five of them fell far outside the accuracy range stated bytheir manufacturers as well as that required by the ASTM standard. These measurements, in combination with the recent review given in [13], indicate that for the IRFTs tested, few, if any, were suitable for body temperature measurement.”A. The most important consideration for an IR fever thermometer is that it respond correctly to variations in human-body temperatures so that one can be assured that the IR thermometer’s reading of (i) a normal-body temperature is really normal and (ii) a fever is really a fever <tinyurl(dot)com/ykeht3fk ; tinyurl(dot)com/yjhe4zc7 ; tinyurl(dot)com/2p8ms693 ; tinyurl(dot)com/fzs5ywee>.B. The infrared emissivity <tinyurl(dot)com/56ex8hmv ; tinyurl(dot)com/6x3em697 ; en.wikipedia(dot)org/wiki/Emissivity> of human skin/forehead is approximately 0.94-0.99 <tinyurl(dot)com/ykeht3fk ; tinyurl(dot)com/y6v7uhj4 ; tinyurl(dot)com/jn2nsurv ; tinyurl(dot)com/6x3em697>.-- Consequently, most no-contact, forehead IR thermometers are calibrated for an emissivity of approximately 0.95-0.98 [but mostly 0.98 <cf. tinyurl(dot)com/ykeht3fk>].C. The infrared emissivity of surfaces of various glass types is 0.67-0.98 <tinyurl(dot)com/mj7nj943 ; tinyurl(dot)com/48by9kte ; tinyurl(dot)com/u7tk2uky ; tinyurl(dot)com/3ukt4jmj>.D. If one were to use my own DIY thermometer-calibration test method below with a container of 0.96-0.98 emissivity, there should be NO difference (i.e., ZERO error) between readings 4.(c)(ii) and 4.(c)(i) below <tinyurl(dot)com/2p8ms693>.===========MY OWN DIY THERMOMETER-CALIBRATION TEST METHOD:===========Below is my own trivially-easy DIY way to check and/or correct an InfraRed (IR) no-contact, forehead fever thermometer in order to validate the accuracy/linearity of an IR thermometer’s temperature RESPONSE at human temperatures between 93.2°F and 109.4°F.-- In the TEST METHOD below, the IR thermometer’s temperature READING will always be higher than the TRUE temperature measured by an accurate digital thermometer (for reasons explained in TECHNICAL BASIS above).I use(i) an accurate digital thermometer <e.g., tinyurl(dot)com/278pbee2> and(ii) a CLEAR-glass container (20-32 fl. oz). A square glass container minimizes off-axis reflections.PROCEDURE:1. Fill the glass container with 16-20 fl. oz. of water.2. Use microwave oven (15-second increments) to warm the water to each of several temperatures (between 94F and 107F) which are typical of normal & feverish human temperatures (e.g., 94F, 96F, 98F, 100F, 102F, 104F, 106F, and 108F).3. For each set water temperature (measured with the accurate digital thermometer), use a spoon or spatula to stir the warmed-water inside the glass container very well to ensure temperature UNIFORMITY throughout the entire warmed-water volume as well as those parts of the glass jar which are in direct contact with the warmed-water.4. For each set water temperature,(a) insert the accurate digital thermometer in the warmed-water to measure the temperature of the warmed-water at any point nearest to the INTERIOR glass wall at a height corresponding to approximately half the height of the warmed water(b) and SIMULTANEOUSLY point the sensor of the IR thermometer at the EXTERIOR glass wall of the glass container at the EXTERIOR point which corresponds EXACTLY to the INTERIOR point where the probe-tip of the accurate digital thermometer is located(c) and SIMULTANEOUSLY record readings IMMEDIATELY for the temperatures displayed by(i) the accurate digital thermometer (viz., the temperature of the warmed-water inside the glass container)AND(ii) the IR thermometer (viz., the temperature of the GLASS container’s wall corresponding to the warmed-water temperature).-- MAKE SURE THAT THE WARMED-WATER TEMPERATURE REMAINS CONSTANT DURING THESE SIMULTANEOUS READINGS.5. For each set water temperature, the difference between readings 4.(c)(ii) and 4.(c)(i) is the error in the IR thermometer’s READING of the glass container’s GLASS temperature due to the fact that the emissivity of the glass container is LOWER than the nominal 0.98 emissivity of a human forehead [i.e., most, if not all, no-contact, forehead IR thermometers are calibrated for an emissivity of approximately 0.98 (cf. TECHNICAL BASIS above)].
