Product review (2 stars): Display has gone bad after a few months.  Not accurate enough....
First off the quality is accuracy is disappointing. I ordered two of these and can place them side by side and they never dispaly the same settings.  Annoying.  I could see a few percent humidity difference and a degree or two difference but they usually read 4 or 5 degrees different and sometimes even 6 degrees different in temperature!  Second one of them already has a defective display and the low temperature reading has some segments out so you can't read it properly (see picture, the lower left should say 70F but some parts of the zero are missing.).

Feature wise there are a couple things I don't like.  First there is no easy way to reset the high/low memory, it seems to remember for as long as the battery is installed, to reset I must remove and reinstall the battery.  And removing the battery cover is too difficult, it is too hard to slide it open.  Second I don't like seeing the humidity on the top. Myself and several friend that have looked at it has said it should have the Temperature on the top and the humidity below.  This is a personal preference of course but it makes sense to me to see Temp first then humidity, several people that have looked at it assumed the top number was for temperature.

The main positive things I can say is that the case is very nice, it feels and looks like high quality plastic.  I also like that is uses an AA battery and not a AAA battery.  If these were more accurate I could probably overlook the humidity on top and would be more happy with them.
