Classic Series Large Dial Refrigerator Freezer Thermometer - Pack of 4

After our fridge/freezer stopped work, it was a couple of days before we realised. Got these to keep a check on the temperature.

Great thermometers, very good price

Easy to read, so the readings might be 2 degrees out either way , but this does not matter, adjust your control if you are that concerned , I think the tolerance on freezer/frig controls anyway are +/- about3%-4%.

See attached photo of all 4 being in the fridge for 3 hours. Readings vary from 1.5 to 5 degrees.

Thermostat Very clear to use and understand

Put thermometer in freezer, checked couple of hours later to find needle had fallen off. Other three in set seem okay so far. Any chance of replacement or do I have to return all four?

One of the 4 thermometers is reading 10 degrees F too low. Not worth returning all 4 to get one low value item replaced, would have liked the option of advising seller that one was faulty, but can't find a way to do this.

Stands or hooks in fridge or freezer as there are four I have others sitting around house to keep eye on temp in rooms
