I absolutely LOVE my Vinator, with a single quibble. I think the spring is a tad long. It doesn't seat well into the 'cup' in the base when I screw it together. So, it sometimes slips to the side, even after screwed together. Since it's done this a few times, the spring now has a 'bow' to it, which makes it even harder to keep seated.
If this is how they normally work, and what happens to them over time (which, I think I've only bottled maybe 250 bottles with this thing) I'm fine with it. It is totally worth it knowing how well the thing works.
As for the foam, I do 2 full pumps, and then drain, and then a partial pump with a slower stroke and then tip the bottle sidewase, it seems to drain most of the bottles out that way.
