United StatesReally, really nicely machined caps with great feel, no complaints there, but bummed out that the "Azure" is more of a dull baby blue than the light icy color in the picture. The "Jade" cap I got is more accurate. Also be warned that stem fit on these is extremely tight, and don't expect them to come with a wooden case or anything like in the photos.
United StatesColor looks great, cap feels great, even sounds great. Love it!
I bought 6 of the Cherry/GMK, one of the SA, and one of the OEM profile caps, a combination of anodized and non-anodized. They are all built to a very high standard of finish, weigh almost exactly as specified (within 0.2 grams), and have the most amazing texture. I feel like part of the reason these aren't as popular is the lack of typical artisan features like embossed characters or icons, enameled inlays, or textured surface relief (e.g. ripples) that are common on metal artisan caps from Rama Works. At $45, these are priced below Rama Works' and no one else is making titanium keycaps with this level of quality. Definitely looking forward to the pin-tumbled and mirror polished options, and I need XDA profile to complete a set arriving later this year. One nit on the profile dimension diagram for DSA profile. It says "OEM, they are all the same" in the middle, when it should say "DSA, they are all the same." Of course, OEM keys have varying profiles depending on keyboard row.
In terms of quality I think there's little that can match this keycap. I love the little pattern on the underside too, shows real attention to detail. Using it feels somewhat like it 'grabs' onto your fingertips and I believe this would be an excellent alternative to homing keys for those that want to navigate entirely by keycap feel alone. I'm personally using to find a key faster even if it's not literally one of my homing keys, it even looks good while doing it too! Best of luck with your endeavours and if you end up making a run of larger keycaps some time in the future (enter keys or similar) I might have to come back for a second round. ;P
