I've just had it a few days, but I really love this thing.. makes rotating models so much more easy.. it also has a couple of buttons on it... what's impressive besides the fine degree of control, is just how solid/heavy this thing is... (order from amazon.com )... I put it next to my mouse, on the right side, and use it there.. it's very very well built, and in fact I like it better than my wacom tablet, though that's a neat tool, too..

it's on the list of "hey why didn't they tell everyone about it?" stuff when getting into 3d modeling.. I wouldn't run my programs without it anymore, esp. poser... it's so easy, and there's no setup, it just works great... (download the latest driver pack from their site and install that, instead of what's on the cd).. sorry i sound like a commercial for this doggone thing, but I really do love it.. it's a "must have" for sure, for 3d work, like coffee :p

you can even choose to turn off the cool-looking blue led light, so it's not distracting... it's neat though, when someone asks about it, you can say "it's my professional 3d modeling control unit" and get that "ooh ahh" look on their face lol
