Just received mine today, and they are awesome. The pink is particularly great as it is completely transparent, while the others are opaque with clear resin exterior. Either way, it's a cool effect if your keyboard has a backlight. Color ranking: Pink > Blue > Black > Red
Hamm3rSounds great, thanks for making sure they're perfect! Looking at the original pics, the colors are definitely off but honestly the cap quality is spot on so I'm very excited.
