Okay, just spent half an hour going through my bag. Seemed to get a lot less symbols than most people but did get the RSS feed poly and a cute little duck my wife has already claimed. Only other symbols are usual OS keys.
Did get a lovely quantity of plain DCS caps in a variety of colors including some clear and jellys, four alps and two of their rounded gamer keys to try.
DSA is what I'm using these days and did get a fair amount of them to play with. A few more colors and maybe a couple of clears/polys would have been nice but I guess they just haven't been made. Did get a bunch of unusual legends, a number of windowed and a few different fonts on them though, see below
Also a large quantity of SS/SA profile to try. Very heavy and slick, unlikely to have enough for a TKL but will be fun to try typing on. About 5-6 of them were semi-clear with a colored red, green or blue transparent center. Probably look cool on a blacklit keyboard.
Unfortunately also had a handful of broken/malformed stem caps and 3-4 handfuls of non-MX mounts including a couple of stem-types, some Cherry ML, a couple of that seem to pinch onto something and some Cherry-MX but-very-small-caps others have already mentioned.
Overall a fun $30. Would be nice if future sets let you choose a profile but I think that's unlikely
