On the announcement, it is about a set of 8 kits (at least that was clearly worded like that when I ordered) ... However, I was delivered a large box which ... contained only one kit! Worse: the kit in question was blue, only missing descriptive color ... Difficult to do less in line with the announcement ... For the record, I note that after my complaint, Amazon was kindly sent another command. After 10 days (!) I finally received a big box with ... A single kit! Anyway, this time the color was indeed part of the promised 4. That's something.
