The MMD Princess Ultra Thock switches are the latest variant of the MMD Princess Series and were specially designed and manufactured for the Bridge75 keyboard. As usual with MMD Princess, the switches type very well and have an even deeper sound than the Princess V4 – Monacokeys. Produced by the latest mold, the new Princess Ultra switch offers smoother and more consistent typing feedback. We've also improved the factory lubrication and bottom material, elevating the "thock" sound profile to a new level – qwertyqop. | The MZ Z1 delivers a marbly sound profile that’s smooth and satisfying with every keystroke. MZ Studio, known for the popular Keygeek Y2 and Y3 switches, brings their expertise to the Keygeek Z1, creating a switch with a smooth feel and a marbly sound – LumeKeebs. |
