As much as I love this kind of technology, I see one major flaw: You can't put coils in parallel. (Of one pickup.) That would be a no-go for me. Humbuckers, and Lil series pickups, in parallel, is one of my favorite sounds. I can't believe they didn't provide for that.
Edit: You can put them in parallel out-of-phase, but that's not useful to me.
But you can. Check out the instructions on page 3.
