Negative Positive
Title: poor accuracy
Review: My unit is installed on the outside of a north-facing well-insulated window so the sun and indoor heat are not affecting the unit. Regardless of this, the temperature always reads 7 to 10 degrees warmer than the actual. I installed a new battery but still is not accurate. This is too large a difference to accept, and like another reviewer said, returning it to the manufacturer is not pratical due to shipping cost. Also, you can't read it when it's dark outside, even if you shine a light on it from inside of house. I like to see the early morning temperature during winter when it is still dark outside. I would not recommend it and am going to try a wired unit instead.
Is the review positive or negative?
