Review on 🌡️ AUTIDEFY LCD Digital Aquarium Thermometer for Precise Monitoring of Fish Tank, Water, and Terrarium Temperature by Leticia Ellis

Bought these thermometers for my various aquariums. I should have tested them right away but I had other things to do so I left them in the package for a while, my fault. I bought 4 packs and out of 4 none show the same temperature as the others. The scary thing is that one was about 10 degrees lower. Good thing I didn't use it in a live tank, I would have turned on the heater thinking the water temp was too low. At least I would have fresh fish for dinner ;) The other 3 were a few degrees apart, all on the high side. The old adage, you get what you pay for applies to these thermometers. Save money and buy something better.
