I have a JetBoil with the french press attachment. Very slick having a water boiler and a french press in one.
As an engineer, I appreciate good engineering. The JetBoil java kit is very impressive in that regard. The new lid has a hole in it for the shaft. The shaft breaks down into two pieces that fits in the mug beside the stove. The strainer fits into the bottom cover. Pretty cool.
Too bad french presses (or are they still "freedom presses

") can be somewhat messy to clean up.
