It fits my hand perfectly and functions perfectly. The extra buttons and programmability make it perfect for CAD work. It also works well with non-CAD software. Having a middle button and a scroll wheel make it stand out. I highly recommend it to anyone using CAD.
Each CAD workstation should have a CadMouse Pro Wireless
I suffer from some RSI pains and sensitivity in my right elbow, so I purchased it to be able to work pain free. Due to the curvature of the CadMouse and the resulting angle to my hand and wrist position, my elbow was not bothered anymore.
Relief of wrist pain thanks to ergonomics
Before giving support to CAD users I have had 7 years of experience as a designer locking my wrist with "ergo" mouses. The added 3rd mouse button is a lifesaver when orienting and affirming actions in some cad applications. I advise it to every engineer indicating wrist issues.
Solving problems for problem solvers
There aren’t many organisations that devote their efforts to making life easier for designers, engineers and architects. 3Dconnexions SpaceMouse and CadMouse products do exactly that.
Reliable, portable, simple
It is the most accurate mouse I have ever used and being able to use customise it for every application is brilliant. It is superbly designed. Simple and intuitive. I've yet to read any manual, it just works the way you expect it to work.
