Mug came with a rust ring on the inside
the warmer works best with the supplied FLAT bottom mug. Unfortunately the mug I received came with a "rust type looking ring" on the inside of the mug. I thought it was cosmetic, so I tried it.......not the case, the taste of my drink was off. If you don't have a flat bottom mug, I would not buy this. It does not keep the drink warm like my old, less pretty warmer.
