GAZZEW U4Tx are an excellent mashup of the U4T and U4, with some extra goodies. The switch features long-pole U4T stem. This keeps the silent upstroke of the U4, while the long pole stem allows the switch to deeply thock uninterrupted by the top out sound. These feature the same amazingly round bump as the U4Ts. Virtually wobble-free, the dust-proof stems are using a box design now. A clear top housing for RGB lighting and a new proprietary plastic for its bottom housing completes the look to match your chase for the ultimate thocky experience!
