just want to say mine were made inUSA!!!! NOT CHINA!!!
If they wont replace it heres a tip I picked up and it works great. Grab a can of spray foam insulation and at the bottom edge drill a hole the exact size of the fill tube and at the top of the neck/edge of the thermos drill an 1/8" hole. Then slowly fill with foam from the bottom until it just starts coming out the top. Using the minimal expansion is your best bet. I used this tip and to say it works great is an understatement. Keeps stuff hot from at least 12-16 hrs.
this company is gonna go under due to this thread.... LMAO
Neighbor just bought his first thermos. told me it said it would keep hot things hot and cold things cold. I asked what he had in it. He said, a cup of soup and a Popsicle...
