For years I had a LaCrosse weather station. Then, it would just drop the outdoor sensor regardless if I replaced batteries in both units. It was also not more than 25 feet away.. I found this on ebay and LUV it. Now, I mount my temperature sensors with strong mounting tape on a wall facing away from the sun. Never had it fall off. I still can't figure out how it determines sunshine as often it's sunny, but will not show. I LUV the color display and keep mine plugged in near my office computer.
