I bought it a few months ago. When it was time to use it, while the little one was wearing it, it showed up to 36 and then the little one dropped it.
After that, it didn't do anything, it just showed 36. And after a while, it never worked again.
I don't know if it's a manufacturing issue or a handling mistake.
Of course, it's expected to fall down when a baby with a fever wears it, so it should have the corresponding durability.
