Digital Fridge and Freezer Thermometer with Alarm

You open the fridge, grab a drink, close it. Three days later you realise the compressor's been running hot and half your groceries are off. This thermometer sits on the outside, sensor inside, and alarms you the moment the temperature drifts past your set limits. No more guessing, no more binning a week of food. Set your min and max in °C or °F, and it beeps until you check. Tap once for room temp too
