Product review (5 stars): Works great.
I have this fridge sitting in my office at work. It does a good job of keeping 6 normal size cans of pop cold. The fan noise is about equivalent to an old desktop computer.  My fridge has been running constantly 24/7 for 4 months now without any issues. The only downside is, once a week, I have to shut it down for an hour or so to defrost the ice.  After that I turn it right back on and it keeps going.

Other than the having to defrost it once a week, the unit is built very well, especially for a novelty item. The door and the latch mechanism still fit tight as it did when it was new. I'm not sure if it was designed to run 24/7, but mine has been going strong without any issues.
