I just made my first cup this morning. Its very good.

16 ounces coffee
2 tbsp unsalted butter
1 tbsp coconut oil

Many advocates of this go full-on, fresh ground, french pressed coffee, and add variables such as cocoa, caramel, heavy whipping cream for taste. I justs used what I had on hand, pre-ground french vanilla flavored coffee. Caramel would have mimiced the creamer I've been using, and I want some now.

You have to blend it until frothy, and as a test I used my spill-proof cup and a blender ball. No mess, no noise, and fast.

Its been described as having appetite suppressing effects, and so far so good there as well.

So far, I am sold.
