Review on 🌡️ VIVOSUN Wireless Refrigerator Thermometer with 2 Sensors: Audible Alarm, Record and LCD Display – Perfect for Kitchen, Restaurant, Bar, Cafe, and More! by Robin Joseph

Pros: This product is well designed and easy to read. They cleverly placed the readings from the two sensors at the top in large type, and information about the surrounding space at the bottom. Cons: I sent it back due to range issues. It boasts a range of 328 feet in the open, so I expected it wouldn't have a problem with my freezer 40 feet away, but I struggled to find a spot where it could reliably read the sensor. My Oregon Scientific has no problem with this range, but it's only designed to measure down to 0 degrees. The other problem is that I got some wild readings the first day or so. I'm pretty sure my freezer set at -2 degrees Fahrenheit (confirmed with a mercury thermometer) didn't reach -12 degrees. The alarm clock woke me up when the reading got so low. If this is normal until the sensor adjusts to the cold, they should let us know. Finally, it would be nice to be able to automatically reset the minimum/maximum temperature on a daily basis. Update: Just before I sent it back I found that the sensors seemed unreliable - the display said it couldn't connect and I had to cut power by removing the batteries. This unit may have been defective but I can only base my review on the unit I have.
