Honestly, I have never seen a more unreliable device. It will either always show 36 to 36.5 even if you are burning with fever, or suddenly it will show 38-39. The scare we got with our child is indescribable.

Not particularly reliable. It changes temperature per measurement on the same person the next immediate second, with a small deviation

If it doesn't show correctly 36.5-36.7. If it goes above 37 it shows crazy things. It showed my child 39.8, I went crazy, I measured again 38.4, I measured again 38.8, then 37.8. I haven't had worse and I bought it from a pharmacy and I'm crying.

Seeing the prices here gives me a headache because I bought it from a well-known pharmacy in my area for €67. It's not worth even €1, you don't even know if it shows the temperature correctly. I calibrated it with a video I saw on YouTube, setting the deviation to 0.3, and I measured my temperature with a regular armpit thermometer and it gave the correct reading. If I want to use it on my husband and child, it gives random results. Sometimes it gets close with a little deviation, but for others, it shows something in the 38s for no reason. Useless thermometer, my aunt bought one for €5 and it works perfectly.

Sometimes the measurements are unreliable

Completely useless..... it's not even worth the 9.90 I paid for it since it terrifies you with its measurements and you need to refer to this mercury thing to make sure....

It's worth its money, very fast, and gives the same measurement every time (in a short period of time), although not completely accurate, but you can figure it out by learning its sensitivity under different conditions (e.g. sweaty, child's skin, different parts of the body).

Having faithfully followed the usage instructions to avoid any misinterpretation, I found that its measurements are completely unreliable. It has been checked on different individuals compared to a mercury and digital Omron thermometer, and the results do not match. Even at the same moment, at different points on the forehead, the deviations sometimes reach and exceed one degree Celsius.

Very user-friendly and accurate. It's worth its money. It measures temperature of the environment, water, and milk, in addition to body temperature.
