Bests & Worsts Reviews from Amazon

I received the stoppers and noted a couple of things. First, I had a couple of these already, which look like the product pictured - grey with 4 vent holes. These new ones don't look as pictured - are black instead of grey, and only have 3 vent holes vs. 4, which increases the time it takes to pump air from a wine bottle. Finally, the center vacuum relief nub has some rubber stems from the molding process still attached - the ones I already had lacked these and were well-finished. In summary, they're usable, but they don't quite feel right, as though they're a knockoff vs. a genuine Vacu Vin product. Then too, it could also simply be that Vacu Vin has changed the design and is going cheaper in it's production standards. ----------- Update - a few weeks later, two have stopped holding a vacuum. Very frustratins. I ran over to Bed Bath & Beyond and - low and behold - they have the real Vacu Vin stoppers that look like the ones pictured in this seller's ad. With that, I have to say this seller is misrepresenting what they're selling, and these are not the genuine article. I'd advise anyone to stay away from this one.
