There are a lot of parts, and no directions that we could find as to how to disassemble/reassemble, but my wife has figured it out.
The plunger performs double-duty as an espresso tamper, although it's not the same size as the expresso holder, which means you'll need to move it around a bit to evenly tamp the ground beans. We used 20 grams of ground beans, and it was a bit messy trying to get them all in there. At 24 grams, I think you'd be a bit frustrated, and might spill a lot.
The press only takes a few strokes to pressurize, and is very fast to make a single espresso. When taking this apart to make a second cup, or to clean, be careful, as there may be hot water left in the top reservoir, or in the grounds. You may want to run some clean water through the device before taking this apart as part of the cleaning process.
The parts are all high-quality, and fit together well. Just don't lose the two silicon o-rings, or you'll have a really nice table decoration.

Excellent to take while camping or traveling on the road. Does make a decent espresso but you do need to pump at least 5-10 times before it starts to dispense the espresso. And then continue until there's no more pressure and all of it has been dispensed in the cup. After washing it , I did leave it to air dry to prevent any molding or rust inside the thermo. As it does leave some water.
