I've always been interested in this model (until I bought a 'syringe' of silicon grease and rolled my own). My only concern with this model was the question of how much grease they apply at the factory. I've only seen one review of this product and the impression I got is that they get rid of the click almost completely (the review was kind of vague on that). Whereas I'd want some click to remain (and I was able to do that by controlling how much grease is applied).

Yep this seems to be confirmed by the seller. He describes the keyboard as non-clicky, even if it retains (a bit of?) tactile feedback.
