MMD Vivian Switch V2: The stem material of the Vivian is modified UPE. We all know that UPE creates a thocky and deep sound profile because of its softness, but softness means it can be easily broken. The modified and strengthened UPE stem solves this problem while still retaining the sound and smoothness of UPE.
Upgrade: V2 upgraded lubrication solution for smoother use and added LED light columns for more even RGB lighting effects.
Features: wider choice of trigger actuation, slightly longer stem, advance trigger, extended spring, top cross-type structure for increased switch stability.
Compatibility: Switches are designed with general MX structure so that they can fit most keycaps sets with (X) cross stem. This greatly improves the compatibility and you can feel free to change the switch and remake your own keyboard.
Pre-lubed: Coming factory-lubed and special structured, the switch can also be self-lubed during every key stroke, which is especially helpful for maintaining a smooth feeling. The durable stem is credited to a smoother and pleasing typing experience.
