Review on 🌡️ 4 Piece Indoor Thermometer Hygrometer: Temperature Humidity Meter for Home, Patio, Planting Room, Reptile Terrariums - Mini Black Gauge by Dan Davis

Bought four. After a while I encountered several problems. 3 of them in the same place differ in readings from 54.1 degrees to 77.9 degrees. Then arrange everything next to each other. Everyone reads differently. I don't know why Revain allows sellers to sell these inferior thermometers. While no batteries are required, they are all made out of poor quality plastic. This is rightly my first review of how bad they are. None of them even come close to the greater accuracy that I have. Also, they all read different numbers, it's crazy.
