My sons told me it's better than French Press coffee: Richer, smoother (less acid) and without the mud in the bottom of your mug. I bought one and they're right.
The biggest drawback is it makes one cup at a time, but it only takes about 90 seconds per cup (once the water is hot). It's also plastic and doesn't take up a lot of storage space so it's great for a boat. I recommend it.
PS -- made in USA by a company that makes a high performance version of a Frisbee. What could go better?
