We bought about a dozen of these for the exterior of our house.  Within moths, even the ones completely covered on the porch were showing signs of rust.  Also, 2 of them stopped working within the first year.  They're the cutest modern-ish ones I could find, so I really wanted to love them!  But i'm disappointed that they're made of low-quality materials that are not suited for outdoor use.  I'd be wary of buying these.  I'm now looking for replacements for my two that will no longer turn on.
