Comments on HMX Caramel Pudding V2 switches | Comments on Unikeys x BSUN Udon switches |
The legendary switch crowned by the custom community as the "Ceiling of HMX Deep Thock" has evolved. Designed by Lucky Pudding and crafted by HMX, the Caramel Pudding V2 introduces the world-first "Waffle Stem Tip" architecture. Paired with a hardened H1 stem and a fiberglass-infused P4 base, it annihilates high-pitch clacks to forge an immaculate, deep "Creamy Thock"—without ever feeling mushy. Enhanced by HMX's 3rd-Gen precision factory lube and a bouncy 22 mm extended spring, this is the most addictively buttery, acoustic masterpiece for your endgame board – Diykey. | The Unikeys Udon linear switch is our attempt at trying to create a clacky BSUN switch that is not thin-sounding. The stem material, Y3X, is the same as the Jade Rosales switches; It can be considered an improved LY or Y3 material, and Y3X is slightly softer than LY but much smoother than both LY and Y3. We chose to pair it with a modified PA66 bottom housing to create a full but clacky-sounding bottom out. The PC top housing gives them a clean and sharp top-out sound. Overall, these will be one of the more clacky new BSUN switches in our collection. In order to prevent the lube pooling issues, we chose to only lube the stem sliders and legs with a very thin coat of 205g0. Springs are lubed with dry film – Unikeys. |
