I bought these for my black GMMK Pro. I have never used MT3 style keycaps, but they feel amazing for me personally. They do take a little getting used to as they are much deeper than GMKs (cherry profile) for example, but after a week or so I can cruise with them. The added benefit is that either because of the thickness of the plastic used, or the shape of the cap, MT3 profile caps sound absolutely amazing. They have a deeper thonkier sound than you get from GMK caps. They probably aren't for everyone because of the shape, but I would highly recommend giving them a try.

Drop MT3 White-on-Black
A timeless colorway, a venerable classic design, and a substantial physical presence make these some of the best keycaps you can put on a keyboard - provided an enjoyment of high-profile, of course. It's hard to overstate how good these look and feel - they really are on another level in a number of ways.
So why not five stars?
A small number of keys weren't injected *quite* right, resulting in thinner and/or less consistent legends than intended. I'm a little unhappy with how the Z and S keys look under close inspection, but that's not enough to keep me from absolutely loving this keyset and recommending it whole-heartedly to anyone who enjoys the aesthetic.
Even with the few and minor manufacturing flaws of this particular example, the quality is shoulder-to-shoulder with the very best out there - and if they manage to QC those few kinks out of subsequent runs, I'd easily class MT3 ABS as the overall highest quality keys you can put on an MX-compatible switch.
ABS is the type of plastic. It is prone to getting shiny over time, but some greatly prefer the feel and sound that the plastic provides.
Doubleshot means that there are actually two plastics used in their creation. One for the legends, and one for the body of the keycap. The image below shows the white legend plastic underneath the black keycap plastic. A doubleshot keycap means that the legends can't wear away.
A keycap profile is a descriptor of its shape. See below:
The MT3 profile is closer to SA (it's a tall keycap), but has some distinct differences. Designed to improve typing comfort and cradle your fingers
Notably, taller profiles lead to deeper sound.
