Familiarity: I've put it through the wringer
I originally bought one a few years back and it is still going strong. It keeps beverages cold for hours, even days. There was this one time I was in southern utah on a backpacking trip. I filled the Growler with a bunch of ice and water when I left my house in Salt Lake. I left the growler in my car for 2 days and came back to a growler with Ice cold water in it. It was a wonderful treat at the end of a hot trip.
Bought another for a present and they love it!
