Product review (3 stars): Extremely basic - needs updated drivers.
Was having issues in laboratory and office at work, so bought these items to monitor temp and humidity.  It does as advertised, but the managing of the data is somewhat annoying.  Instructions are basic, but not completely clear.  Would not install on a Windows 7 computer, but works with XP just fine.

You have to set it up every time you off load data.  It doesn't automatically restart.  Off loading the data doesn't clear it, and it will not restart on its own.  Just a minor annoyance.

You cannot rename the device, so if you have multiples your are trying to manage, you have to be careful not to mix them up.
