I ordered an SA escape key for my Vortex mechanical keyboard that uses an OEM layout and the difference between the SA keycap and the OEM keycaps is a really nice touch that potentiates fact it's a novelty key.
It's a bit bigger than the OEM keycaps with a wider base and just makes the escape key really stand out and look fantastic. The quality of the keycap is top notch, the white font is perfect and it's simply an excellent keycap. Period.
I will be ordering additional keycaps from here as shipping is also quick.
