Although I've been told that the packaging for the concentrate tray was not yet finalized, I can say that the packaging I received came with an extremely well made information booklet about the tray. Kudos to MF for being so thorough in their documentation that explains usage and tips. I liked how the pamphlet was part of the packaging as well with the concentrate tray screwed into the middle (hard to describe). Also I would like to note that it is quite easy to overfill the tray. MF suggests a small dab the size of a match head. That is the perfect amount IMO. I tried loading about 2 match heads worth and when I melted it down in the tray, quite a bit overflowed into my screen. Performance hasn't been affected, however.
