“Thick” O-rings are a great option if your goal is to reduce key travel significantly.
They will bottom out just after the key’s registration point and simulate scissor switches on laptops or thin membrane keyboard, but still retain the “mechanical” feel - along with increased cushioning.
These thick O-rings work flawlessly with almost any stock keycaps from companies like Corsair - Ducky - Cooler Master - WASD Keyboards - Filco - KÛL - Das Keyboard ... and more generally with most "OEM" profile keycaps.
But they are, on the other hand, too thick to be used with lower profile keycaps made by manufacturers such as GMK - JTK - BSP - Leopold - CherryCorp or IMSTO.
There is one exception, though, namely the Cherry MX Board 6.0 keyboard (G80-3930) which has slightly lower keycaps than "OEM" profile ones, but still compatible with these 2.5mm thick O-rings.
