Product review (1 stars): Bad decision.
Most of the reviews talk about the questionable humidity reading, but the outdoor temperature is off by as much as 10 degrees.  I have moved the sensor unit several times to different locations around my house - sun, shade, mix.  It doesent matter.  They are all off.  I would return it if I could, but I kept trying to find an effective location.  Gave AcuRite the benefit of the doubt.  Bad decision.
