I found this wireless home weather station at Radio Shack for $40. I get home and the instructions say don't let the exterior sensor get wet. Excuse me, its an exterior device and it can't get wet? It's part of a weather station and it can't get wet? I didn't bother to install it, returned it right away. Has anyone found a good, wireless weather station that can actually stand up to the weather? Please point me in the right direction.
