Works as described. It fits pretty well on the Exo Terra glass terrarium; however, the background that the terrarium comes with partially obstructs the hole that the probe cord is supposed to fit through when using a glass top. It will eventually fit, but it's a tight one. Additionally, it leaves the glass lid a bit ajar (not enough for frogs to escape through thankfully). I've had no problems with accuracy thus far, but I only just got and set up the probe.

I compared this to another combometer and they were showing the same thing basically. It looks nice sitting on top of the light rails as well and is very easy to read

Very happy with this temperature and hygrometer. It seems to work very well and I have tested the accuracy with a cigar hygrometer that I know is very accurate. It seems to be very accurate and it fits right on the top of the vivarium. Roger K5MOW

Best value around.

My first combo meter worked great for years. recently I bought a new one from Josh's and it was broken, reading 99% humidity. they sent me another, which again gets stuck at 99% humidity, usually at night but not during the day, which is strange. Josh's gave me a refund, but I would watch out for this issue
