   I know the owners manual and website say this item is only good for outdoors if left dry and above 41 degrees, however I can honestly dispute that.

   I have had 2 of these clocks outside in my backyard since December 2005 (over 4+ years).. no issues at all. The 2 clocks outside are on a fence where it gets beat up by all the storms and hot sun… as well as this past winter, we got down to 8 degrees (yes, 8 degrees in Dallas)…. the clocks are both still running great! absolutely no impact by the storms or deep cold. The other is mounted on the house where it gets beat up by the cold, sun and heavy steam from the Hot Tub… also no issues.

   So regardless of what the website or owners manaual says, I can vouch that these clocks work great over many years in deep cold, strong winds, heavy storms (and yes, getting totally soaked) and direct Texas Sun.

   I HIGHLY recommend these for all

   I bought this item as a gift. Before giving I wanted to set it up for the recipient. I followed the instructions and had it working briefly. Once wrapped, I heard the hands cycling quickly around the clock (as if searching for the correct time). I unwrapped it and called for tech support. They offered some options, mostly changing the battery. Once done with that it began running at the proper speed, but was off by 3 hours (for every time zone). I’m done with this hassle and returning to amazon.

   I have had this clock on a screened porch for about two years. It is amazing! I have only changed the battery one time. It keeps excellent time and it has automatically changed between standard and daylight saving time without a problem. I highly recommend.

   I’ve had this clock for about a year. It worked fine throughout the winter even in -10F temperatures. 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.

   This model is appanently the same as the cheaper WT-3181P. 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. in southern Arizona. Amazon needs to add this important note to its product description.
