Received these 2 days ago. The first day I pulled the plastic from the battery compartment and put them in the small box I’m currently housing a box turtle until the large house comes in. One of them is about 5 inches from his basking spot, which is about 10-12 inches below a 50w UVB bulb, all inside a bedroom. It read 41 degrees. When I woke up, it was still reading 41 degrees. I took it out, took out both batteries, wiped them carefully with a lint-free cloth, made sure the connectors were good, and replaced them and then the unit. Put his lamp back on. 6 hours later it reads 44 degrees. The other was near his hide, away from the lamp. It also read 44 degrees the whole time. I know my room isn’t 44 degrees, so I’d have to say these are definitely not accurate.

1 month in and work great! (Don't mind the cold temp on the thermometer in the background of the picture I had just moved the little guy back into his enclosure after a clean. )Easy to set up. Came with a sticky pad to stick the thermometer to the tank. I should have placed the pad directly on the back center of the thermometer but I was worried about removal for cleaning and battery changes so my sticky pad is sticking out on top a little and bugs me a bit.My only complaint is that they can "pull apart" easily. My husband tried to help me clean the tank, unaware of how fragile these thermometers are. He went to pull one off the tank and pulled the casing right off! The thermometer fell into 4 separate pieces (button, front casing, back casing, and circuit board). He put it back together and it appears to be working fine. Just keep this in mind when pulling them off!

These work great. I’ve washed the tank with these on there multiple times the adhesive hasn’t budged. Super easy to read and apply. They are super durable. The only thing is try not to get them super wet they took a few days to dry out on the inside So the humidity said 95 for like 3 days. But after that I’ve had no problems with them. Great effective design.
