Gazzew Boba U4T Tactile Switch Review | LumeKeebs

Overview

When it comes to "thocky" switches, the Gazzew U4T Boba V2 is second to none. The "U4" stands for "Euphoria" and the "T" stands for "Extra Thocccc." The Gazzew U4T Boba comes in several variants: an all black housing, a clear RGB top with black bottom housing, an all white housing, and a clear RGB top with white bottom housing.

Gazzew has designed a new leaf to be both compatible for both linear and tactile switches. The new leaf also helps to reduce leaf ping.

Here are some sound tests of the Gazzew U4T Boba V2:

Switch Feel

The Gazzew U4T Boba are extremely smooth with little to no scratch. The Gazzew U4T Boba have very little stem wobble due to its tight housing tolerances. The Gazzew U4T Boba has a very pronounced D-shaped tactile bump.

Things to Note

If you plan to open and close the Gazzew U4T Boba to do any modifications, like lubing or filming, we would recommend to check if the legs on the top housing are fully seated into the bottom housing. Since the housings for the Gazzew U4T Boba have very tight tolerances, it requires relatively more force and attention to close the top and bottom housing together. Lubing the Gazzew U4T Boba can help provide even smoother keypresses, but filming doesn't appear to be required snice the Gazzew U4T Boba already has a tight housing.
