I've had it for about a year. It's good and seems accurate, as the temperatures appear to be as expected.

The thermometer was reliable for a long time. Suddenly, it starts showing a higher temperature, and because it had already broken in the past, we thought that the refrigerator had broken again. Just in time, we managed to cancel the service to repair the refrigerator. By placing two other thermometers next to it, we found out that it was showing eight degrees higher than the other two thermometers!! I checked the battery issue as well, but it was fine. Also, the display was very bright and there was no sign of any problem. I no longer trust it at all! It went for recycling...

Quite good, now if it measures correctly I don't know, I tested it next to the gas thermostat and they have a difference of 0.4, now which one tells the truth no one knows, I think it's worth it especially to put it inside refrigerators etc. to see temperatures and generally in rooms or wherever else you want

It looks very good. I bought it for maintenance and the only negative thing I found is the hook, which is not convenient for hanging, at least for the vegetable drawers that I wanted to put it in, because it doesn't have a proper grip, resulting in improper contact with the wall.
In the end, I put it on a shelf of the door, which, as expected, shows a higher temperature than the rest of the refrigerator.

Very easy to use, it reads with precision. In the vertical grill, of course, you can't hang it as it is with the parallel hook, so I came up with a solution. Clear screen, helpful, beautiful! Just so you know, it's not suitable for deep freezing because it only measures up to -20°C.
