I had them on my Poker 2
I thought they were great. They have a nice texture, and they're very thick. They made a very satisfying low pitched clack when typing compared to cheaper thin ABS caps.
My ONE issue with them is that the vertically stacked legends (on keys with an alternate shift function) results in only one of the two legends being illuminated as you can see in my photo. The number row in particular bothered me the most, since the symbols were illuminated, but not the numbers.
I've heard that Vortex is actually in the process of redesigning this very keyset with horizontally opposed legends to solve this issue, but that version of the set isn't available yet. I hope when they release the updated version they offer a number-row-only option for people with the old set that only care about the number row.
