Ok so I have been running these for a few days..The colors are awesome in this keycap set, and quite honestly all of the Osume caps are nice, but as I suspected the legends are small. As someone else mentioned it does offer a different look to the board, which is nice and clean. If I am wearing my glasses the legends are fine and I don't look down much to type so it's not a huge issue, but still learning to live with it and adjust.
I will say, the difference in sound between these keycaps and GMKs is large. These are much less snappy, more of a cream to the sound-I understand they are different plastic compounds. I have a copper plate so it's a decent match for the PBT Plastic still has some pop-I think I just got used to the GMKs. Again I love the colors, but to anyone looking at Osume who prefers large legends look twice because they are VERY small in real life.
