Query: Looks nice but....

It is a nice looking mug. The big problem I had with it was that I wanted a stainless mug. Unfortunately in the description it failed to mention that the entire interior is plastic. So, if you are trying to avoid drinking out of plastic this is not the mug for you. I can not rate it as to the function because mine is going back so I can get a true stainless mug. It does look like it would be a great mug if you didn't mind the interior being plastic.
