Thank you for viewing! I am offering a custom set for the G300s and G300sr mice. This improvement will transform your G300s or G300sr into something completely new. ・Dress-up rubber: 1 set ・Silent micro switches: 6 pieces, made by HUANO [Dress-up Rubber] This rubber sheet is applied to the contact surface between the mouse and your fingers, repairing the deterioration of the mouse's original rubber and improving its appearance. The feel will also become more comfortable and familiar to your fingers. The kit also includes an alcohol sheet to remove oil and grease before applying the specially cut rubber sheet. If the sides are sunken, it is recommended to fill them with epoxy bond or similar before applying this product. After years of use, the side rubber can deteriorate and the click areas can become shiny, but this product can renew them. [Silent Micro Switches] Durability: 30 million cycles (30M) Set quantity: 6 pieces Manufacturer: HUANO Excellent silent performance. The "click-click" sound of the standard switches is improved to almost silent. If you listen closely in a quiet place, you will hear a slight "pecko-pecko" sound. However, the tactile feel of the click is still present. The clicking sound of the mouse is a combination of the sound of the mouse itself, but the effect is still significant. ※ The standard switches used are rated for 10 million cycles, so Replacing them with this kit will improve durability. ※ The standard switches are D2FC-F-7N (10M) made by Omron. Compatibility is not an issue. ※ Disassembly of the mouse and soldering are required for replacement. ※ The sound will not be completely eliminated. The G300s and G300sr are already discontinued. Why not renew these classic mice with original customization and enjoy them with a fresh feeling?
