Review on Vacu Vin Saver Vacuum Stoppers Kitchen & Dining by Brenda Young

I've had a vacuum set for over a year now and it works great. The original plugs will hold a vacuum for several days (probably a week or more). These plugs won't keep the seal for more than a few hours. I've looked closely at them and compared them to the originals and honestly I don't see any difference, but they definitely don't work. I used the pump as usual but when I returned to the bottle the next day there was no vacuum and I was able to pop the cork without resistance. I also didn't hear the air rush in as I pushed the nipple aside to break the seal. I returned them and wondered how to get more jams.
