Customer Rating: Summary: Not the Best Vaccum Pump Comment: It seems to do the job, but I was not that impressed with the product. It does not take out the air to the extent that I would like it to. I have another one which is slightly bulkier with larger stoppers, but that one works much better. It is better than nothing, though. I guess you get what you pay for. Customer Rating: Summary: Not a wine opener Comment: I actually thought I was ordering a wine opener, but it turned out to be a device that takes the air out of the bottle (of wine)so it stays fresh longer. If I had not looked this item up on google, I would still be puzzling about how you get the darned thing to open your wine. No directions or literature comes with it, so you have been warned. Well made and I'm guessing it works very well, but I have not tried it out yet. Customer Rating: Summary: good product for a good price Comment: The wine pump works just as advertised. be prepared that it doesn't come with extensive instructions or a fancy box, but it's a pretty simple concept. I have had it for over a month now. Customer Rating: Summary: Looks good, Works good Comment: Pump has a nice look and finish. Works great, only five or six pumps and a strong vacuum is created, making for a solid seal. Comes with two stoppers; I rarely have multiple bottles opened at same time. Holds vacuum for at least 5-7 days and probably longer but haven't kept bottle sealed longer. Customer Rating: Summary: No more cork bits Comment: I think this is a much better way to reclose the wine as there are no cork bits to get into it. It fits perfectly in the neck and is easily removed at ones convenience.
