So far, so good.  I store medicines at 63F with ambient of 70 to 73F, so it is not working very hard.  It keeps things fairly constant, makes a little more noise than I expected but that lets me know it's working, and it was easy to remove one shelf.  Lowered rating because it has been here only a couple of weeks and the ambient temperature hasn't varied much to actually test it.  I expect all will continue to be well, in which case it will get 5 stars.  Really looks nice.  Glad it is not really Black & Decker, only someone renting their name.  Exactly what I expected from the ads.
