Thank you for viewing! I am selling a customization set for the G300s and G300sr mice. This customization will revitalize your G300s or G300sr. ・Dress-up rubber: 1 set ・Silent micro switches: 2 pieces [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. It also provides a better feel and grip. The kit includes an alcohol wipe to remove grease before applying the custom-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 refresh them. [Silent Micro Switches] Durability: 30 million cycles (30M) Quantity: 2 pieces Manufacturer: HUANO Excellent silent performance. The "click-click" sound of standard switches is almost eliminated. If you listen closely in a quiet place, you might hear a faint "pecko-pecko" sound. However, the tactile feel of pressing the button is still very present. The clicking sound of a mouse is a combination of sounds from the mouse itself, but the effect is still significant. If you leave a comment, you can increase the number of switches for 100 yen per switch. It's reasonable to replace the switches you use most often. ※ The standard switches have a durability of 10 million cycles. By using this kit, the durability will be improved. ※ 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?
