Bests & Worsts Reviews from Amazon

First bottle of wine I used it on was not that good. After contacting the seller, I just had not pumped it enough, very hard cork in that bottle. All the other wine bottles it has worked great. That first cork was very dry and I even broke it with my screw type extractor trying to get it out. I would buy them again, they work great, just use a little more pressure pumps on extra dry corks that are hard to remove.
