If indoor, it should stay dry. If outdoor, it should be protected by GFI in case of it getting wet. I personally don’t worry about it any more than any other item. Anything can fail, and assuming that “one” failure of a given item is flawed by design is not something I do. Sometimes a superior item just happens to fail for unrelated reasons (unrelated to design). I need significant statistical data to conclude one is worse than the other. The smaller size itself doesn’t bother me at all.
