Query: UPDATE 5 Stars (from 2 star thoughts after 10 months - Lining problem

UPDATE: About 8 weeks ago, I went back to Target and saw that the instore samples had no lining so bought a third one and and it has been PERFECT :)It is again my favorite Thermos.OLD COMMENTS: I bought two of these April 2008 (one for my me, one for spouse) and we use them 5 days out of 7. I was originally thrilled by the fact that coffee poured in at 6 am was still perfectly hot and enjoyable at 4 in the afternoon. My spouse's Thermos, (he drinks his coffee black)still seems great. But my Thermos(I use cream) started having flakes inside a few days back which I now realize is some sort of lining (teflon like?) comming off. YUK! I have carried a Thermos to work for 20 years and this was my favorite by far until this "lining" failure. Anyone else experience this? Maybe I have a "lemon".....?
