I was told by a couple of people who work in wine that they didn't feel like it was worth it.
No doubt there would be some benefit, but don't think it would be any better than a coravin with the screw cap accessories (which sucks btw).
I personally wouldn't pick up a pivot - we were at a relatively fancy restaurant today and saw one sitting on the bench, they were using vacuvin for the by the glass wines... we've been to a number of CDs that do use the screw cap attachment (Clonakilla comes to mind) and I've seen them used at Muse in the Hunter. Pivot just seems like an attempt to tap into a more casual market.
