My Haier beer fridge has been running strong for nearly 7 years now.
I was going to say, I've got one of those as well. Back around 2009, somebody left it out by the dumpster for the sole reason that their dog had been chewing on the cord. I replaced the cord and gave it a thorough bleach cleaning, and it worked fine. It's been in continuous use since as overflow storage (first at my sis & BIL's house, now at my folks' house) and still going.
Our church kitchen has some old Frigidaire unit that was rescued from a cabin damaged by the Big Thompson Flood in 1976. Still working, although given the location, it doesn't get opened and closed too much, and correspondingly doesn't run very often. The main reason to upgrade is that any unit older than about 2000 or so probably uses at least 2-3x as much energy as a modern unit.
