First off, it's hard to imagine a product less supported by the factory than this one. Avid bought this product line from Euphonics, and it took them about a year just to get their name on the case! When you call the mother ship for help, the place is not teaming with expertise.
It was designed to be used with Apple's Color program and FCP7, which has been all but run over by Blackmagic's DaVinci Resolve (with a fully working free version if you can keep your files under 2k).
It works just fine with Resolve, but it was not really designed to do so. Worry not. It works well.
It hasn't always! The ECON driver system was the flakiest piece of software in my facility for years. The latest version (first quarter '14) works well and is recommended.
I would rather have the 20k controller made by Blackmagic specifically for DaVinci Resolve. But if you, like I, are 18k or so short, this will work just fine.
And it's worth the money. Color correcting "with the balls" is a far more accurate, efficient and satisfying experience than choking a mouse.
As always, Sweetwater's service is first rate.
