Gazzew Boba U4T

Manufacturer: Outemu
Brand: Gazzew

The U4T Boba switch is a medium tactile switch with a D-bump with no pretravel on the downstroke, a solid bottom-out, and a nice pop on the upstroke. The stroke all the way through is smooth, thanks to the housing and stem material composition, and has a thocky bottom-out that has become very sought after. Gazzew has also gone to the effort of designing a new leaf to not only be linear and tactile friendly, but also to reduce leaf ping. The use of high-quality Korean stainless steel springs helps prevent spring ping as well.

U4 is short for Euphoria.

The "T" in U4T stands for "extra Thocccc".
