Product review (1 stars): Battery Eater
We placed our sensor in the shade and have found it to be accurate.

However, since purchasing this product in June, 2016, we have replaced the batteries three times because the display goes dim and then out. It needs new batteries yet again.

Our other, older unit -- a different brand -- has not needed any new batteries during the same time span. We're going to replace the AcuRite this time instead of putting another set of batteries in it.
