I use it for 6 months to control Logic Pro 7 and iMovie is class!

So it's a jog / shuttle that simply plugs into USB-compatible Mac (PPC or Intel), you just set yourself commands for more flexibility, but once done can not be without it!

Very cheap (50 €), so I would definitely do it again this election. I just wanted to find the white model so that it matches the Mac, but the details ...

I put only 9 because the config is still not super clear ...
