Its been almost exactly a year since I've bought these and reflecting now, I wouldn't buy them again.
I've been using these on a keyboard at work exclusively. I'm a software developer and I type more than people usually do, but not nearly as much as other people, like gamers, use WASD. Black paint started to come off and the keys are turning fully transparent in those places. Ever since I got them they felt cheap. Cheaper than the original keys on my Ducky keyboard. The edges are also somewhat "sharp". I'll follow with a photo once I get to work next week, but have this in mind when buying them. They wont last forever. They do look kinda cool though.
