Product review (3 stars): Seems to be pretty accurate however the outside unit eats batteries
Seems to be pretty accurate however the outside unit eats batteries, the inside unit is still running on the original batteries placed in the unit about 6 months ago, the outside unit batteries need to be changed every 4-6 weeks and I'm not living in a cold climate. If you see the signal strength meter is gone then that means the outside unit has stopped transmitting. Simply pop in new batteries and wait or if you're impatient then pop one of the batteries out of the inside unit for 10 seconds or so then put back in, this resets it and it should now start showing you the proper temperature.
