Hi John - Ive now been using mine for a month.
The flow is indeed quicker. But in comparison to the Synesso baskets - small but noticeable improvement IMHO.
Only did one back-to-back comparison, and slightly muffed the grinder setting so the shot via the VST was a tiny bit fast. The two shots tasted too close to pick, but the one I did immediately after with the grinder tweaked a bit more was lovely. But that could be wishful thinking..
I do love the way the puck just drops clear too! I suspect I might be getting the single version when it comes out (I have the 18g).
