Product review (3 stars): Not as good as it can be
This product seems to work OK in general. I have 4 of these and they all have different humidity readings but are close except for one. (had them all on the same table side by side) One has a humidity reading of 10% (always) even in the bathroom taking a hot shower. It only changes if I hold it over boiling water. For temperature they all seem to agree as long as they are in the same location. So over all this product works fine but I think in the future I will try something else.
