We, however, are working just fine and showing the temperature correctly. I have compared it with other thermometers and also have the sleeping bag from this particular company, very satisfied

So much money for the temperature to show whatever after 2 years of use (and not daily but occasional use). We have 27-28 degrees in the house and it shows that we have 23-24... The light is nice but it's not worth the money

I paid 40€ and damn if it has ever reached the temperature once! At home, I have 20°-22° and it shows 26°-27° in the winter.
We thought we were going crazy and we were wearing robes in the heat!
You understand that this is dangerous, given that it is combined with the baby's sleeping bag and you choose a sleeping bag based on the room temperature. It needs to be plugged in and it comes without an adapter. Sometimes it goes crazy between temperature units (e.g. between 22° and 21.9°) and it flashes, and it turns red when it is high. I won't describe what it does to the child's room.

I would like it to have a cable for the socket and not just USB because I had to find an adapter. Only for this reason.....

It is perhaps the most useless accessory for the baby. In mine, the temperature sensor does not work well at all, resulting in showing wrong indications almost always. The only nice thing about it is the night light, but it is not worth getting a whole thermometer, it simply takes a light...
