He has still a small flaw ... The standard software which is actually part of the trackball to say the least scrap, unless you want to hear a lot of music or infinite increase in special programs images. For all other users - Software Exchange.
The alternative software of Kensington, called TrackballWorks, the 4 buttons assign any shortcuts or other commands. What the software unfortunately still can and will hopefully change soon, that you can also specify combination circuits free. The so-called chording. On the website there is indeed advertised already busy, but in the use of my software version 1.04, this is not yet possible. Perhaps there will even do something in the future. This probably seems to be a development error because you have the trackball precisely designed to "Media Control", but it is almost all users would demonstrate the keys like free.
From the processing and the function I can only say that it is a great product, also an eye-catcher on the desk / workstation. Ergonomically well designed for optimal comfort you should order now with a wrist rest, because in spite of everything else, a slight bending angle occurs like a mouse.
Conclusion:
+ Full-featured mouse replacement (had previously Logitech Performance Mouse MX)
+ Very good ergonomics
+ Processing
+ Optics
+ Easy to use
+ Precise control of the cursor
- Until another software designed to take advantage of trackballs from fully
- Still no choir Dings (shortcuts) possible
