Product review (1 stars): Dreadfully inaccurate
Inside temp is more or less accurate but the remote sensor is way off.  Read an outside temp of 43 when it was 26 (and no, I didn't have it in the sun).  Moved the sensor inside and after letting it acclimate to room temp put in my reptile tank.  Read a temp of 71 when in reality it was 82; read a humidity level of 38% when it was 75%.  Totally undependable piece of junk.
