Product review (1 stars): Very Dissapointed
I had a previous model of this item for many years that was very reliable.  This one doesn't work at all.  in the several weeks I've had it, the indoor portion records the same outdoor temperature no matter what it is.....58 degrees even when its 30 outside.  Etvery day I have to take off the back, take out the batteries and reinsert them.  then it resets and works for the day.  The next day its back to 58 degrees.  Not a product I would recommend if you're looking for accuracy in temperatures.  Sorry I purchased this.
