I’ve had no issues with this Escali thermometer for adult forehead and object readings (not sure about ear accuracy), and it seems quite accurate for a digital thermometer in those modes. It has adult, child, ear and object temperature modes and can be switched from Fahrenheit or Centigrade. It can store readings. Fortunately, it’s intuitive and easy to use as the print is small in the instruction booklet. I took pictures so I could enlarge it enough to read it.
I’ve been using the adult forehead and object modes and get readings consistent with devices I trust. I’ve compared the Escali to a similar “no touch” thermometer for home use and get identical or very close readings. Both gave me 98.3°F forehead readings back to back, and the biggest difference has been .3°F after taking many readings over the course of a few days. The Escali needs to be positioned 0-3 cm (0-1.18”) from the forehead, and instructions say the forehead reading is indicative and can fluctuate up to 1°F.
I’ve used the Escali object mode to take home air temperature readings, and Escali seems quite accurate compared to my thermostat. My thermostat is in whole numbers and Escali readings are in tenths, so there could be some small variance within a degree. One thermostat reading was 68° F while the Escali reading was 68.1° F and another time it was 61°F while Escali was 61.4°F. The whole number on my thermostat has always matched the Escali.
I can’t fully assess the accuracy of the Escali for taking a child’s forehead reading or an ear reading (which is taken with the cap off). I’ve taken ear readings and they’ve been within .7° of my forehead readings and seem typical of my normal temperature, but my ear readings have been the lower temperature at times. I would think the ear reading would be higher than the forehead reading. So I don’t know if it’s accurate.
I like the Escali for its ease of use, and it seems reasonably accurate (within the stated 1°F margin) for adult forehead and object readings. I use the forehead mode as an indicator of fever rather than a precise reading. I’m uncertain about the ear reading accuracy and am taking a star off for that reason. I use a traditional thermometer if any digital thermometer (or symptoms) suggest a high fever. Two AAA batteries, a storage bag and instructions are included. I like it but have reservations about the ear mode. 4 stars.

I am not especially a fan of the new digital oral thermometers that have been on the market in recent years; they seem to be of questionable accuracy. I still have a mercury thermometer that is quite accurate and we have trusted for years. Measuring on the forehead or in the ear has been the standard measurement method recently and I was interested in trying this one to see how well it works. It seems to be accurate and it works well, though I say this with a caveat.
This is a very straightforward and easy-to-understand unit. Point it at the forehead and press the button, and a reading comes back within a second or two. The display is bright and big and it is very easy to read the temperature on it. The display itself is one reason to consider switching to this kind of thermometer. When I compared with my mercury thermometer, the results actually were fairly close together which was a surprise to me – I expected the digital thermometer to read low.
Removing the rubber end on the measuring side reveals an ear canal measurer. So, if you don’t trust the reading off the forehead (and there are reasons this might be a valid concern, see below) this thermometer easily converts to one that measures the temperature in the ear canal instead.
One of the main issues with this type of thermometer, and it is not limited to this one in particular, is that the surface temperature of the skin can vary a bit. If you sit in a well-ventilated area and continually get a draft the temperature will read low (I measured 94.7 F after sitting in an air-conditioned car with the air blowing in my face). If you spend time in the hot kitchen before measuring it may come out hot. And, distance from the surface factors in too. While this isn’t necessarily a bad way to measure, it’s important to remember that a number of factors can skew the result.
For a forehead thermometer, this one works well. It seems to be reasonably accurate and it measures quickly. Just keep in mind that accuracy is impacted by where it is used and how far from the surface it is held when measuring.

Product came half hanging out of original box inside the Amazon bag and the batteries that were to be included were missing

I received this product for free through the Vine program.
This thermometer is very similar to the multitude of touchless thermometers available on Amazon. They all work similarly and are reasonably accurate for measuring forehead temperatures (this device claims +/- 0.4℉ accuracy) and are simple to use. This device has a couple of distinguishing features. First, it comes with its own cloth carrying pouch. Most of these thermometers come in a flimsy cardstock box which will eventually get crushed, frayed or torn, leaving the thermometer susceptible to scratches or damage to the sensor. Second, this device can take ear temperatures by removing the magnetic sensor cover which reveals a thinner sensor tip which can be pointed towards the ear canal. That could come in handy if you can’t get a reading off the forehead.
I tested this thermometer with multiple readings which were all pretty consistent and within the normal range. I did use warm water on a paper towel and checked its temperature which confirmed that it would read a high temperature.
This device also has a mode for measure the temperature of household objects. It is less accurate in that mode. I measured the temperature of various objects that had been in the refrigerator for hours and the temps ranged from 34 to 44℉.
Overall, this is a very usable touchless thermometer. The carrying pouch and ear mode are its distinguishing features.
