    And I am giving many stars but I respect that it is economical and it also respects my wallet, it does not deceive me. Do not expect accuracy in your measurements, it's more about having something to talk about, but its price is like that of a cheese pie so it is understandable, you get what you pay for as the wise people say

    I got it for an experiment with the children at school (to see how different materials behave under the influence of the sun - urban heat island effect). It had large deviations, or I did not use it correctly

    Works well, but I had to finish the laser pointer myself, otherwise it was not clear on what surface it measures the temperature. The thing is definitely useful, it lies in the nearest drawer in the hallway, I used it 100500+ times

    It has an issue with the measurements... When measuring on my skin, it shows 30-31... At a time when I should have 35-36... It says it has a deviation of 1.5 units but this one misses almost double that... Not to mention triple the percentage and a bit more... But never mind... I'll keep it in mind and mentally add a little more...

    For the use I got it, it's quite good... I mainly use it to measure the temperature of the pizza stone before I put the pizza on top. Now, in measuring room temperature, it still seems quite accurate.

    From the beginning, it seemed that something was not right... I tried it at the standard boiling water temperature and it showed 85 °C... in measuring body temperature, the mercury thermometer showed 37.8 and the digital one showed 26°C... wasted money... such a shame...

    It is good. I believe it is not accurate. That is, it does not show the real temperature. But I use it indoors and keep the relative measurements. For example, if a surface always showed 30 degrees and the next day it shows 28. I don't know if these are true numbers, but I believe it's close. For me, who is interested in relative values and fluctuations, it does its job. If I wanted to measure food, I wouldn't be sure it shows the exact temperature.

    There is a huge deviation from the actual temperature, up to 10 degrees. This mainly happens in negative temperatures.

    Flawless, with great accuracy in measurements, cross-checked with other thermometers. I bought it for my baby, for his milk, for bath, etc. and it solved my hands, by far the best solution. The build quality seems fine.

    Very helpful and easy to use, I measure liquids, solids, and metallic objects in the car, etc.
    Very good measurement accuracy (we're not in F1 looking for perfection) for its price.
    Lightweight, easy to grip, takes 2 AAA batteries instead of a 9V, so you can find and replace them at any time, they go in the handle.

    It does what it promises, measures with laser or infrared depending on the choice you make, the temperatures seemed accurate in 2 heat transfer presses that I set at different temperatures, very good for its price.

    It worked for about 6 months and its measurements were accurate. After this period, suddenly it started showing +300c no matter what I measured, and since then it never worked properly again.

    4 years later, it works without any problem. It has a slight deviation in measurement, but for the job I need it for, it's not a problem. I bought it to make soap, but ended up using it everywhere, from measuring water temperature for bathing to cooking, frying, and such. It has fallen countless times and the plastic has broken in one spot, but it still works. One time, I left it in the sun and it got very hot, it went crazy and showed random readings, but as soon as it was in the shade, it returned to normal. For household, non-professional use, it's great, just keep it away from children because the laser can harm the eyes.
