Product review (5 stars): Works as advertised so far.  A little more involved than "stick on and install lock" however.
There isn't much of a selection of this type of locking device and they are a little expensive for what they are.  I paid $45 for a mini fridge on sale and $20 for this device plus $5 for a combo lock.  So far so good, it works well.  The only issue is the instructions say to use 90+ lbs of pressure to make sure the 3M adhesive bonds properly then not to put weight on it for 24 hours while it cures in 70F+ temperatures.  90lbs of pressure is quite a lot for a mini fridge, but I pushed as hard as I could without denting the fridge and it seemed to work.

UPDATE 1/9/18:  After using this for a couple months it's still holding up great.  I love it.  Very solid.  Hopefully I never need to remove it because that doesn't look fun.  Just a note to anyone putting this on a new fridge:  you might want to use the fridge for a week or two and make sure it isn't defective before installing this lock.  Mine wasn't, but I didn't test the fridge at all and got a little nervous the fridge might be defective and I'd have to try removing this lock and returning the fridge.  Luckily it all worked great.
