Product review (1 stars): Inaccurate
I am very disappointed with this product.  We purchased this to monitor the temp and humidity in our living space and in our son's room.  When I initially set up the system, I followed the instructions. Put the batteries in, screen turned on- signal was good and it seemed like it was all set.  I sat the display and wireless sensor on the counter in the kitchen about a foot from each other and of course got pulled away for some reason or another.  When I came back, the two readings didn't match.  If the display takes a reading and the sensor takes a reading right next to each other, shouldn't they both be reading the exact temperature and humidity.  Everything I have tried to fix the problem has not helped.  I have put the wireless sensor in another room and the outdoor sensor consistently shows an extremely lower humidity value.  Next step is calling the company but if they can't help, I want my money back.
