Product review (1 stars): not worth the money
well i am not happy with it,  i have had it one day and already problems.  last night when it was about 40 outside, it told me it was 161 degs outside and the unit was locked up  also showed low battery, when there were new ones inside.  i took out the batteries and put them back in and it came back up working.  i never touched the outside sensor.  this morning it was locked up on 40 degs and 90% hum. Outside and the inside temp was also wrong. i remover the batteries and put them back in, it jumped to 54 deg.  I don't thing location is a problem, because the sensor in on the other side of the wall outside and 5 ft away.
