Title: Vacuum insulation failed after six months
Review: I used this thermos to bring my coffee with to work with me. Then it stopped insulating.I'll admit that it worked very well for six months, and I used it every work day. My coffee stayed very hot. Unfortunately, it now won't keep my coffee warm for more that an hour or two.I never dropped it, or slammed it against anything. It has no dents in it, and the stopper still works fine. One day it kept my coffee hot, the next day it didn't. The insulation just stopped insulating.It only worked for six months, that's not acceptable. A quality product would have lasted longer.
