Review on 🌡️ Thomas Traceable Refrigerator/Freezer Plus Thermometer 4527, with Vaccine Bottle Probe (5mL), Temperature Range -58 to 158°F by Fred Novak

Just bought two for domestic fridges. Set the alarm thresholds to 32F (low) and 45F (high). One of them reset the alarm settings once (return to default 50F/86F causing false alarm). I swapped it out for a decent battery and removed the cheap one that came with it. The second restarted several times with false positives on different batteries. The second has returned and the plug-in resets more often than the first. So send back the replacement for a refund. The first one seems to behave, so I think I'll leave it alone. I bought two of these for the home freezer in 2014 and they have NEVER had a reset problem. They are still in use today.
