Excerpt: I use it mostly in sketch up pro & it's really worth of the high price if you make 3d as a pro. Previously I had some problems with my regular 5 button mouse during zooming & the work was not so smooth like now. I tried it also with autocad 2009 for 2d purposes & it works very good, as well. I tested the stuff with google earth, but I wasn't impressed. Anyway it's pricey product so I recommend to buy it only for business.
Summary: The idea is superb and it is a vast improvement on moving your hand to the keyboard every other move however, there is no tactile feedback on which key is about to be pressed and at this early stage (only 2 wees of actual use) I'm still hitting the wrong key too often.
Summary: I've been using this for just over a month now (I avoided writing a review before now to avoid "New Toy Syndrome"). I bought it to replace my dying Space Navigator. That served for more than 5 years of abuse and neglect without issue. The SpaceMouse Pro is a worthy addition to the 3dConnexion line up and, depending on what you plan to use it for, worth adding to your kit list.
