Super Easy to Use
I need to take my son's temperature three times a day and the thermometer I currently have is one of the organic ones, which are super good, but they take a while to rise, so I bought this one that measures in an instant by infrared, from the brand The outer casing of the thermometer is made of plastic material, measures 5x5x17 and weighs about 110 grams. It has two modes of use, for the ear or for the forehead, to use it on the forehead you have to use it as it comes, to use it in the ear you have to remove the cover from the front so it is more anatomically shaped. It has a screen that indicates the temperature, the screen changes color depending on the measured temperature, white (start), green (normal), orange (mild fever), red (high fever). I really like it, you can measure the temperature in a second and even without touching your forehead, which is great.

A must have for all but especially so for parents. 👍👍👍
With two young children, a good quality and accurate thermometer is a must have in any first aid kit, irrespective of whether it's likely to get frequent or infrequent use. I chose this one because it's non-invasive - meaning no intrusion and more importantly no spreading of germs. Also because it's supposed to take accurate readings in 1-second measurement, with zero waiting time. Inside the box is the thermometer and a grey velvet like drawstring bag, and the instruction manual. A quick start guide too. This particular thermometer focuses all its efforts on taking infrared readings by pointing at the forehead or in ear readings, assuming this works and works accurately. Also, as it is non-invasive, you can take temperature readings whilst the child is asleep. Thankfully, the manufacturers have seen fit to supply two AAA batteries so all you need to get started is to fit the two batteries in the back of the thermometer. It has a fairly large and easy to read LCD display window whether the display is illuminated or not. Within the display are also some icons - a house (room temperature), ear (indicating ready for in ear reading), a baby (differentiating between 0-6 years, 6-12 years) and adult (12 years +). There are three actual buttons on the thermometer - measurement button on top of the display (the trigger button), baby - adult button (to reflect the age of patient) and an "M" which is used to switch between room and forehead or ear readings (keeping the M pressed down for 5 seconds enables the memory - the checking of earlier readings). To measure, press the trigger button, point and release the trigger button. It does indeed provide a reading after 1 second. Suggested distance between reader and forehead is 1cm - 3cm. Forehead readings : - Readings between 32° - 37.5°C, the thermometer display will light up green and beep - Readings below 32°C, the display will indicate "Lo" (red illumination) - Readings between 37.6° - 38°C, the thermometer display will light orange and beep - Readings above 38.1°C and the display will illuminate and flash red. The fever warning This range is pre-programmed. Other points of note - Pressing down the trigger for 5 seconds will turn the volume either on or off. - Can alternative between Fahrenheit and Celsius - Also, the thermometer automatically shuts down after some seconds, so battery should last ages. According to the manual, forehead readings tend to read between 0.2° - 0.8° lower than rectal (I intend to believe this and definitely no plans to prove it 😊). Also that a woman's body temperature generally is 0.3° higher than a mans. So far so good, but the real test is how do results compare ?? Very well actually. Based on a sample set, and not uncommon for these types of thermometers, I got to an average 0.3-0.4°C difference when comparing forehead to in ear readings, which I am led to believe is on par forehead vs in ear. In ear constantly consistently delivering a higher reading but not materially different from the forehead reading. Overall I am very satisfied. It does indeed does its job well and quickly and therefore I cannot ask for more !!

Does the job
It does a good job, but I don’t always get the same reading which is why I gave it 4 starts. I am not convinced in accuracy but definitely tells you when the fever is high. I love the added little light that blinks discreetly every so often so you can find it even in the dark and be able to use it. It would be pertinent if you could silence the beep it makes once the reading is complete so you don’t have to wake up children.

Ended up returning as it was faulty
Had the item for a couple months and the device started to become faulty and started giving false and inaccurate readings so we returned back for a full refund. Seller did not respond to my messages

Temperature is inaccurate
My braun that I had for 13 years finally bit the dust so I purchased this a year ago based on cost and reviews. Kids are now much older so doesn’t get much use and I am well used to the old fashioned touch test so only really use a thermometer to confirm. Child had tonsillitis but it kept saying temp okay albeit I was a bit dubious but child wasn’t burning. Child definitely has a fever/ temperature today and is burning but it is again showing around 36. I have never known it go above 37. Am going with my gut that this is faulty, binning and just purchased a braun again.

Great product
Great product for babies and putting my mind at ease. It’s small enough to carry around, and I’m happy the readings have been correct. Easy to use and value for money

Great product… except I can’t tell how accurate it really is
We bought this because we needed one with a backlit screen. This one is simple and easy to use, and offers ear, forehead and room temp options. However, having used it a few times alongside another ear thermometer and an armpit one, I seriously question the accuracy of it. It was adamant that me and my wife both had a temp of 36.8 even though I could feel she was burning up - sure enough the armpit thermo said she was well above 38. When measuring room temp it also read 1.5-2 degrees colder than the room thermometer in my daughters room. Clearly more testing would need to be done but I’m pretty sure it under-reads by enough to be significant.

Produit livré très rapidement par Amazon Prime comme d’habitude rien à redire. Le produit est conditionné dans un carton, et le thermomètre est protégé par une housse de transport. Fonctionne avec 2 piles AAA fournies dans l’emballage. Son utilisation est très facile, il suffit juste de permuter entre le mode adulte ou enfant, et le tour est joué. Point positif ce modèle permet une prise de température frontale mais également auriculaire pour les bébés par exemple. Les données des dernières prises de température sont enregistrés. Indication de la température par signal sonore mais également à l’aide du rétro-éclairage de l’écran qui change de couleur et vous alerte. En comparaison avec mon ancien thermomètre classique digitale, la température correspond parfaitement. Achat très pratique vu la conjoncture actuelle et la crise sanitaire. Simple et efficace. Merci Amazon pour ce produit. A recommander 👍🏻

La misurazione ovviamente non può essere perfetta, ma l'indicazione di temperatura fornita è comunque abbastanza stabile e affidabile. Alla fronte restituisce generalmente mezzo grado di più rispetto alla temperatura misurata all'ascella con il termometro classico, ma questa sorta di "tara" è stabile quindi nessun problema. La misurazione all'orecchio invece è in linea con quella del termometro classico. La temperatura di questi tempi va monitorata spesso e questo termometro a infrarossi consente di avere all'istante una misurazione di massima corretta. Utile soprattutto per i bambini.
