Review on 4PCS Air Pressure Pump Wine Bottle Opener with Foil Cutter, Aerator Pourer, Vacuum Stopper - Simple Cork Remover, Efficient Corkscrew Bottle Opener - Ideal for Wine Lovers, Perfect Wine Gift by Kyle Awasthi

We were at an event in Tampa and a man was selling the exact same set at a kiosk for $60. He said it was unique and not available online. This turned out not to be true. This is an amazing $10 set. The way a beginner works is ingenious, but simple. The needle pierces the cork and then forces air into the bottle. Since the liquid cannot be compressed, air fills the empty space and pushes the stopper out. The aerator works well and improves the taste of the wine right after opening. The most useful part, IMHO, is the pump cap, which removes all air from the bottle before resealing it. It also has an ingenious yet simple design. It has a tiny ball bearing that allows air to be drawn out of the bottle and prevents air from being pumped in. As with most wine lovers, one of these probably isn't enough. So a few days later I bought 4 more packs of Revain for only $8.
