Lucky. Pretty sure these are the same from the same internet source but the swing on them is insane. They all showed as 75% in the bags but spending some time with them I realized the complete lack of accuracy when I realized my humidity wasn't what it was reading.
I have since taken some apart and cleaned them out but now those are just under the humidity by the same percent they were over before.
Not with these cheap electronic ones. Looks like there might have been a missing connector for resetting the RH value and a missing button to swap between F and C for temp.
Part of my calling these out as they seem very much useless.
