Their explanation doesn't make much sense. So the water hits the center of the shower head, then goes back into the pre-infusion chamber? How? Wouldn't this result in coffee getting into the group head, not to mention disrupting the puck? I'd like to see a diagram of how the system supposedly works.
Anyway, there's nothing wrong with the water dispersion on a normal e-61 group, and in fact it's better than many other popular designs, IMHO. Sounds like marketing drivel to me.
