High-Caliber Performance in a compact form factor The CadMouse Compact is the ultimate wired mouse specifically suited for design and engineering professionals who prefer to use a compact form factor for their hand size and grip type. Demonstrating our refined precision technology in a compact body, it is ideal for those who frequently switch environments, requiring faster and more agile movement. Compact Ergonomic Design 3Dconnexion has met a design challenge by introducing a dedicated middle mouse button despite a compact size, which allows to reduce the required actuation pressure up to four times less. This provides a more delicate, precise click requiring less force than scroll wheel clicks on traditional mice. It also reduces the muscle and tendon discomfort frequently encountered during long working sessions.
