"Not fit for purpose"
Bought this as advertised to check the temperature in the fridge and freezer. It is useless for the freezer because it won't indicate a temperature below -18. It just shows LL.L so you cannot tell if the freezer is too cold, or at least by how much. But worse the battery holder is so loose that it keeps falling out. I have had to tape it in place with sticky tape. A small issue is that it only seems to update the display every few minutes, which can be confusing.

We're sorry you're disappointment the thermometer doesn't measure below -18 and we're sorry to learn of the problem with the battery holder.
