Love ceramic lined interior

I absolutely love this 12 oz RTIC mug. The ceramic-lined interior keeps my coffee hot while preserving the true flavor—no more metallic taste when sipping. It feels well made, comfortable to use, and is perfect for enjoying coffee the way it's meant to taste. Highly recommended.

My preferred brand of cups

I tried Stanley cups. They fell over too easily, and they didn't hold as cold as this brand I currently own three of your cups, a large, one, a medium one and a coffee cup! for me to spend money on 3 cups tell you something about the product! Because I don't waste money this is not a waste. This is an investment in myself !

Perfect

Love it but with this one you need to keep that lid close if not it gets cold faster then the other ones for me it's ok because I don't like to burn my mouth when I drink tea
