It's ok – GoodDual Display for Mac Review
It works, but it's a gpu hog, even with my MacBook Pro 15 with dedicated gpu, graphics stutter on computer and iPad more than would be expected. Video playback on either screen is unwatchable while in use. Even switching between screen sets in os x is hesitant. High power and energy efficient settings on Mac app don't seem to make a difference.
