I purchased this, but after receiving it, there was a part that interfered with the main body, so I've shaved off a portion for adjustment. I've designed and manufactured a dedicated angle stand for the Logicool ERGO M575 and the silent model M575SP, from 3D design to production. This stand tilts the mouse, reducing strain on the wrist and arm, allowing for comfortable operation even during extended use. I felt a sense of discomfort with other similar products that only offered horizontal tilt, so I designed and manufactured this myself, and after repeated prototyping, I've achieved the ideal angle. - 20 degrees horizontally and 15 degrees vertically, allowing for mouse operation in a natural hand position. - The simple design keeps manufacturing costs down, offering it at an affordable price. Please try this stand to create a comfortable working environment. ※ The mouse body in the image is not included.
