Product review (4 stars): Improvement needed in the insructions?
This is the 2nd AcuRite 00611a3  purchased. The first received was returned being inaccurate. Being my 3rd AcuRite thermometer product, I found the AcuRite products price fair for the quality offered.
The one returned may have worked, if there were instructions on how to place the sensor unit on the outside of a window. I found the sensor gave a closer to accurate reading when the blinking red light faces away from the window. If my observation is correct why there no mention of this in the included instructions? May be it is peculiar to my location? I would welcome to hear from them.
