Bought these because I'd been eyeing them for a while and needed caps compatible with south facing LEDs. The side legends were perfect for that. These keycaps are great for RGB in general.
Quality wise I didn't experience any of the issues with scratching or missing/duplicate keys that others have commented on but be aware that drop support will be unwilling to provide any single keycaps for nonstandard layouts (such as an extra B key for Alice boards), even for a price.
These keycaps are very loud. When I put them on, my keyboard was 2-3x louder than the cheap keys I'd previously bought from another site. My personal preference is for a silent keyboard, so I ended up ordering silent switches to solve this problem. I do think the sound profile of these keycaps is what the average keyboard enthusiast prefers, though.
