Title: Doesn't insulate
Review: I purchased this to replace a small thermos I'd had for many years; I use the thermos daily to bring coffee to work. My husband had the larger version, and liked it. This smaller thermos does not insulate. Hot coffee is cold within an hour. At first, I thought that I was not tightening the lid sufficiently; not only did tightening the lid not solve the problem, but over-tightening the lid made the thermos impossible for me to open once I got to the office. I had to run hot water over the thermos in order to get the outside to expand sufficiently to allow me to get the lid to budget. I have quit using this thermos and am looking for a replacement thermos.
