Query: only looks nice

It looks fantastic but it is the only feature. When I opened the package, it showed that the temperature was between 68-72. After that it never changes! Even I put it in the fridge for two minutes, nothing happened at all. I am sure my refrigerator works well, so I just returned it. By the way, the service of Amazon.com is excellent.
