Product review (5 stars): I would easily have expected some sort of rattle
Typically I don't review items.  I thought that I should for this item however since it has outlived the beatings of what I would assume any appliance should not have to go through.
My wife bought this for me about 4 years ago to put in our basement.  It worked as expected and then one day our basement flooded.  I ended up finding this on its side in about a foot and a half of water.  After having it sit and dry out and finally getting around to see if it worked after about 6 weeks, I was surprised that it worked as if nothing ever happened.  I cleaned it out and it has worked ever since.  Perfectly.
Since then we have moved twice, once to a temporary rental house and again 10 months later to a new home.  At the rental house it was in the garage where it was bumped into on more than a couple occasions by the front of our cars.  Still no issues.  I was moving it down the stairs into the basement of our new house and on the last step, the hand truck got caught and the fridge flipped over, hit a wall and landed flat on its side.  Once I plugged it in, it still works.  I would easily have expected some sort of rattle, vibration, something but nope.  This things still works.  I'm shocked.
I highly suggest this mini fridge.  Maybe the trick is not to baby it.
