Thermometer + Hygrometer Choices?

[seks]

Any body have any luck with these (Zilla thermometer hygrometers)? I'm looking for some different readers and these looked pretty shnazzy. I wanted to go back to exo teras version however the readings I got from them in the past were pretty off. Any body have experience with readers that can take heavy humidity saturation? What does every body use for there setups?

How were you able to determine that the ET thermometer and hygrometer readings were off?
