La Crosse Technology WT-3181PL 18" Atomic Outdoor Clock Reviews
It worked fine throughout the winter even in -10F temperatures. I've had this clock for about a year. In the summer, it catches some late afternoon sun, but this doesn't seem to have harmed it. The original alkaline batteries are still working.
The instructions say it can only be used outdoors if protected from rain and above 41 degrees. Its 27 outside right now. I guess it might be O.K. This model is appanently the same as the cheaper WT-3181P. Amazon needs to add this important note to its product description. in southern Arizona.
