Comments on BSUN Mozzarella Cheese switches | Comments on MMD Princess Tactile Ultra switches |
Keys in Cheese Studio has done it again. This time, an interesting mid‑leaning tactile that can move toward clacky or thocky depending on configuration. Closest comparison would be newer‑generation HMX tactiles: quite poppy, a bit bright, but mostly mid‑toned – SerpentKeys. Mozzarella Cheese Switches by Keys in Studio and BSUN are tactile switches with a mid-leaning tactility that have quite a neutral sound profile, accentuated by the keyboard configuration – Divinikey. | MMD Princess Ultra are the latest version of the MMD Princess switches. These switches now feature a nylon bottom housing for even more thock and an LED diffuser for improved illumination. Thanks to the newest molds, tolerances have been further refined and stem wobble significantly reduced. As always, they come with excellent factory lubing and the signature smooth typing feel—these switches remain our absolute favorites! – MonacoKeys. |
