Received my product today and super happy with the quality of it. Comes in a package that we can keep in easily. There’s even batteries that came with it in the box. The thing is pretty simple to function after reading the manual. There is 2 modes that came with it too. One was for forehead testing while the other was ear temperature testing. I tested out with 2 of my housemates and they were accurate! So a plus for that! We also plastic wrapped the tip before placing it in the ear for hygiene reasons, the readings were still good! There are 2 temperature units with Fahrenheit and celcius which you can easily change at the battery compartment. There’s a small switch there where you can just flick it to have it changed. I placed the thermometer on my friend’s head and then press and hold the button and in seconds it was done after hearing the beeping. Then brought it up to check the readings. The thermometer will tell you if it’s wrongly done and that’s probably when it tells you the sign “Lo”. The good thing is you can literally test the forehead and then take out the black tip to test the ear which was honestly easy to use! Super happy with the quality and the product itself. Would 100% recommend to anyone who’s looking for a good thermometer that is simple to use and has good functionality.
