Product review (5 stars): This thermometer was so easy to set up
This thermometer was so easy to set up.  The instruction booklet is well written in U.S. English.  I have a multi-hundred dollar outdoor weather station and the remote temperature from this AcuRite does agree with my outdoor weather station.  The AcuRite humidity is within plus or minus 15 percentage points of my outdoor station, i.e., it is not accurate. If you wish to have an accurate outdoor temp, this is a really good device at a very low price.  If accurate outdoor humidity reading (or indoor) is critically needed, you will not find it with this instrument.  That observation is not unexpected.  Measuring humidity is not easy and usually requires much more expensive components.  Any device less than $100 can be expected to provide an estimate of humidity and not an accurate value.  With that caveat, I strongly recommended this AcuRite device.
