I had a nissan thermos, and loved it, kept stuff hot for a long time, then I got stupid, overfilled it one day, screwed the cap down real tight and blew the seal... good bye nissan.... I bought a new one and it never did a good job, it was nothing like the original one of two years earlier. I figured I just got a dud, bought another one about six months later, same thing, they just don't do a very good job anymore..... I have not had any problems with my stanley, I used to have one of those stanley bolt's and it was great also. I just wish I could find a good thermos now that can hold about 2 qts. I really don't trust nissan anymore.
