Title: Buy the better one
Review: After a couple of weeks of using this, I noticed an off smell. Got out my tiny bristle brush & cleaned the inside top really well. Actual chunks of grossness came out. Had to clean it with the brush each evening in order to use it. Ended up throwing it out. They now make a wonderful mug that has a hinged design so the inner workings open up for cleaning. Much more sanitary & it cleans beautifully.
