As a fan of all things Star Trek, I love the mug style and quality is great. I should have paid more attention to the size when I ordered it. Most mugs are larger, this one is smaller then I prefer. I usually have 10 or 12 ozs of coffee, and this is designed comfortably for 8 ozs. Being a coffee lover as well, I can't enjoy as much coffee with this mug, so I ended up enjoy the mug more by looking at it, rather then using it.
