I am very impressed with the quality of these keycaps. They are very thick and consistent throughout the set. There are no problems with double exposures. They are indeed very similar to the original GMK olive set. Actually, my kit came with a sticker on the big box that said GMK Olivia White. Although definitely not packaged like a real GMK set. They're a bit slippery, so keep that in mind if you always have dry hands. Can't say enough about how good they look, feel and fit the board. The only real gripe with them is the 1.25u key spacing, which deviates slightly, but it's not the biggest gap you'll notice. Additionally, the new pink enter button is slightly wider at the base than the rest of the rows and protrudes slightly at the end of the board. You really have to look closely to spot this problem.
