I'm using SpaceNawigator everyday and this is a great help. This "toy" increase productivity. In near future I will buy SpaceExplorer. I use SpaceNawigator mostly to SolidWorks and SolidCAM software. In first touch is hardly to operate but after about 30 minutes you know how it works and how operate. Before SpaceNawigator I used other manipulator so I had a knowladge about adventages this solution. I'm highly recommend this "toy".
