I got 4. They work just fine without any significant deviation. In fact, I added 25 meters of cable to one for the solar panel and it only lost one degree.

I have had one for many years and I still haven't had to put in a new battery. I just bought a second one now. Compared to another thermometer I have at home, it shows exactly the same temperatures (so either both are good or both have the same error)

Its batteries were low, it didn't work, I had to buy new ones. After two days of use, it was showing completely wrong readings and the screen was flickering.

very good thermometer I got one for the house and the other for the computer. you can also measure car air condition temperature, it should normally be in the car where it comes out below nine degrees. not above nine.

I found it just fine. Of course, I immediately put in a new battery. It didn't work at all with its own.
It even fell down and nothing happened to it!
Someone writes that it changes reading easily. Of course, because it is accurate! I keep it in the fridge.

it is not accurate and the temperature changes very quickly, either inside the fridge when I open the door, or outside the fridge

It is convenient and quite accurate. Get an extra battery or two because I got 2-3, one (if I remember correctly) had a dead battery.

It does its job just fine. I got it for measuring the temperature of the solar panel by using a phone cable extension, and so far it seems to have enough accuracy.

Pretty good, but when I put it in the freezer, it freaked out. The screen turned white and came back after I took it out, after about 20 minutes. For maintenance, anyone who gets it is just fine

It loses about 0.2 degrees in a test with a professional thermometer! For its price, excellent! There is a possibility to be installed flush somewhere!

extremely useful, especially now with the high temperatures, for immediate monitoring of the temperature of the refrigerator, office computer space, and wherever else deemed necessary.

As you can see in the picture, they are quite reliable in accuracy, the battery inside, in 2 out of the 5 thermometers, was not working. Cheap construction but when it costs "nothing"

It has fast response as it is for an aquarium.
I use it for the refrigerator and freezer and I am very satisfied!

Always the review and rating are based on quality and price.
I bought it for measurements in my refrigerator because we had a problem. So I bought 2, one for cooling and one for freezing. Their measurements are fine. Now, if they were accurate to the decimal point, I can't say for sure. But for the job I bought them for, excellent! In external temperature, they showed approximately what I understood we had (e.g. 35 degrees Celsius). So they helped me a lot with what I wanted. Obviously, if someone wants it for professional use, I don't know if it will be equally satisfactory. However, a professional on the other hand cannot have tools worth 2 euros on him :)

I bought 2 a few months ago and now I bought another 2 for my business refrigerators. They are simple, cheap, and user-friendly! They also seem reliable for now, at least to the extent of accuracy that I need!

It does not have an on-off switch. It is not waterproof (it does not say anywhere on the package that it is waterproof, of course). I do not know what sampling rate it has. I do not know what reliability it has.

I have two refrigerators, so I bought two thermometers. I put both of them in the same refrigerator to test them. See the photo. Which one is correct? Is any of them correct? I have no idea. I need to buy a third one!!!

Very good for its price. However, I would prefer it to have a sticker on the back so I can stick it to the refrigerator door.
