After trying it out for about a week, the short and sweet of it is that these look, feel and sound really great! I'm so over the moon with this!
I was looking for a set of keycaps to give my current keyboard not only a deeper/"thockier" sound profile, but also have a go at a non-uniform profile, which led me here. Now I have quite the penchant for classic/retro things, so natch this would the 1st set I'd look, having typed on a Qwerty-profile PBT rec of these as can be seen on the side. The side-printing of the Commodore is simply good aesthetic, kinda why I picked this.
Having replaced my XDA profile that came with my System76 Launch keeb for this one, they do make a difference in the sound and feel and overall well adapted to it thanks to the Qwerty profile as well as the wrist rest. However that keeb's surprisingly difficult to mod keycap-wise because of its non-standard layout without either going all-uniform like XDA or even R3SA, or splurging on the majority of these sets. But I knew of that and wanted to give the latter a try.
Out of the wrappers (seriously they look like dark, ruby and matcha chocolates out of the box!) the keys themselves are a little on the matte side and can reflect a bit of light. I did hear about some disadvantages like how ABS would shine over time, would yellow in adjacent sunlight, or the stem wobble on SA being more extreme. Despite all these, I'm really enjoying these so far without a hitch - the doubleshot does almost all the lifting.
As I said, the S76 Launch is a heavily-modified 75%/TKL layout, which leaves some keys looking out of place, like R1 1.5u backspace, R2 pipe\| key, R3 1.5u caps lock (separate key bought from another set,) R4 1.5u RShift and two 2u split spacebars which I got in PBT. Some creative liberty went through to match to the layout I wanted, although I might plan on getting an 1800 layout keeb in the future (yeah I'm deep in this lil hobby :p)
It's very pricey even for the base set and those with VERY non-standard layouts it can burn quite the hole in your wallet, but considering their longevity and frequency (or the lack thereof) of swapping keycaps, I'd say it's worth the investment if you can afford having lots of spares lying around for maybe some macro boards.
You do kinda get what you pay for, which is quality, resilience and above all - style, so props to that!
