Query: Had to return it

I was just looking for something small to put under my desk in my office to keep my lunch cold (you know, sandwich, yogurt, standard stuff). The unit is a great size, but really doesn't get cold enough. I kept this running for 3-4 days, thinking that maybe it needed to gear up for a while and get colder, but no luck. The back wall of the unit gets pretty cool, but the inside cavity does not. I finally had to return it and was told I'd only get a full refund if the unit was defective. They ended up charging me a 20% or so "restocking fee" for the return and said they tested it and that it worked fine for what I had been trying to use it for. I respectfully disagree. If you're looking for something to get soda about 10 degrees colder than room temperature, this is your product. If you're looking for a small fridge for your office, keep looking.
