The amount of travel you have with different keycaps is related to
A: How tall the keycap is. OEM profile is supposed to be 11.8mm (12mm profile)
B: How thick the reinforcement bars are. Some keycaps do not even have reinforcement bars.
C: How long the "stem" or "mount" or whatever u want to call it, is.
D: If the keycap is made at a screwey angle that could affect things too.
Thank you for reporting this! I was thinking of buying those same keycaps. Travel distance is important to me!
If you could post an upskirt shot of your original keycap vs. one of the new keycaps side by side, make sure they are both the same exact key, that would help us to evaluate the situation.
