Good to check fevers
Iâm always doubtful with items like this but this one passed the test. (Only use it on humans). On foods itâs too hot and wonât read.

Super Fast, no contact infrared thermometer.
Works great, and has a slim compact design that feels good to hold.Wish it didnât run off batteries, and the screen would light up green/orange/red to indicate temp range.

Nice thermometer
I like it so farUPDATE: i use a sensor to control my blood sugars but I need to have a monitor to check it every once in a while To make sure that the sensor is working correctly so the second time I went to use this thing, the lancet got stuck and will not release the needle, so it’s completely useless. I have tried everything and nothing works.It’s just stuckIt’s broke second time in use.

THE NO-TOUCH THERMOMETER THAT COULDN’T TOUCH THE TRUTH
THE GHOST THERMOMETER: READINGS FROM AN ALTERNATE REALITYIf thermometers could gaslight, the iHealth PT3L would earn a PhD in psychological warfare. I purchased this $25 contactless wonder for our newborn daughter, thinking armpit readings might traumatize her delicate baby existence. Instead, this high-tech mirage decided to haunt me during what I suspect was a brush with the norovirus – or as I now call it, “The Great Internal Organ Olympics of 2025.”THE SETUP SAGABattling what felt like death with a side of misery, I somehow managed to install the included AAA batteries and unfold instructions resembling those impossible gas station maps your dad keeps in the glove compartment. The device immediately revealed its first personality quirk: a learning curve steeper than my fever spike.THE IMPOSSIBLE GEOMETRY CHALLENGEUsing this thermometer requires holding it EXACTLY 1.8 inches from your forehead – not 1.7, not 1.9, but precisely 1.8. When you’re collapsed on the couch with the energy of a sloth on sedatives, accurately gauging this distance feels like attempting brain surgery while riding a unicycle. The angled design makes self-testing an Olympic sport in spatial awareness that I wasn’t qualified to compete in while my brain was medium-rare.THE TEMPERATURE FICTION FACTORYWhile my standard thermometer confirmed my internal bonfire at 100.5°F, this digital deceiver insisted I was a refreshing 98.3°F – essentially telling me I should be frolicking through meadows instead of contemplating my own mortality. Even more baffling? Now that I’m recovered, it reads me at an impossible 96.7°F – apparently, I’ve graduated from “perfectly healthy” to “walking popsicle.” I’ve included photographic evidence of this temperature fantasy for posterity.THE FEATURE OVERLOADThis thermometer comes equipped with more modes than a spaceship control panel: memory function, bottle temperature, baby mode, adult mode, and a mysterious “custom” setting. I’m sure if I had read ALL of the manual (which felt like homework assigned during a fever dream), I might understand their purpose. But when you’re sick enough to contemplate writing your own obituary, decoding technical manuals drops to priority #437.THE DESIGN CONTRADICTIONPerhaps the most perplexing aspect is the silicone pad at the end of the device that practically begs to be pressed against your forehead, yet the instructions specifically warn against this. It’s like putting a steering wheel on a toaster – a design element that contradicts its own existence.SCIENTIFIC DIVERSIONSIn a moment of desperate entertainment, I tested it on my trusty Corgi. The results were inconclusive but strangely satisfying. Science cannot explain why measuring a dog’s temperature with a contactless thermometer brings joy, but I stand by this research.â PROSContactless design theoretically perfect for sleeping babiesBatteries included (the only straightforward part of this experience)Multiple temperature modes that someone, somewhere, understandsMemory function for tracking your journey through fictional temperature landsMakes for an excellent prop when playing “starship captain” with a toddlerà CONSAbout as accurate as a weather forecast from a psychic octopusThe 1.8-inch distance requirement defies human spatial perceptionSelf-testing requires the flexibility of a contortionist and the aim of an archerConfusing silicone pad that contradicts usage instructionsConsistent 2-4 degree underreporting makes you question your own realityFIELD NOTES”Mom hands” provide more accurate readings than this $25 digital deceptionEven a glass candy thermometer would provide more reliable resultsIf you must use it on yourself, find a mirror or prepare for temperature rouletteSave your receipt. Frame it. It will be your only souvenir from this thermal adventureTHE VERDICTAfter a brief but memorable relationship with this thermometer, I’ve concluded that it had one job – accurately reading body temperature – and it failed spectacularly. At $25, you’d be better off developing the ancient parental skill of forehead temperature assessment via hand. When battling illness, the last thing you need is a medical device that tries to convince you your raging fever is actually hypothermia. If you’re shopping for a way to monitor your newborn’s temperature, keep looking – this device exists in its own thermal dimension that bears little resemblance to our own.

Digital thermometer

Doesnât pair with app
The item works fine however it does not pair with the iHealth app (either one). Will work as a regular thermometer but since it wonât pair itâs of no use to me. This model is t even an option when the thermometer options come up.Kind of deceiving that all iHealth products pair.
