Gazzew U4Tx are an excellent mashup of the U4T and U4, with some extra goodies. The switch features long-pole U4 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.
The Gazzew U4Tx switches blend the deep "thock" of U4T bottoming out with the quiet stealth of U4 topping out, offering a refined sound profile and a sharp tactile bump for a luxurious typing experience.
The switch housing features a clear top and a bottom made from Gazzew's new proprietary plastic blend, the new shrapnel design increases the sense of touch and reduces the noise of the shrapnel (due to the metal composition and the new plastic base), and the light paragraph touch and linear touch are very friendly.
The normal version is compatible with any lamp beads (SMD, four-pin, two-pin lamp beads), and the RGB version is only compatible with SMD lamp beads (SMD). They are compatible with hot-swappable sockets (Kailh & Gateron universal sockets.
Factory lubed: Leaf is factory lubed, but slide rails/rail-slots are dry. We don't feel that they require lubing, but we leave that decision up to the customer.
