Reads humidity reasonably accurate, and fast.  When moved from my dry box to regular air it measures RH change very quickly.  I think at the lower parts of RH scale its off, seems not read below 10%RH.  Overall I would have given it 5 stars if I could change the temp scale to F.  I would buy this again.
