Review on Electric Preserver Automatic Intelligent Silicone by Michael Walker

Sometimes I can't finish a bottle or open a few bottles of wine and I want them to be fresher than just a cork. I've used a manual pump wine preservative so far, which has worked great, but makes you wonder if you pumped enough to get all the air out. This electric version is great, works automatically. and although I didn't wait 7 days to make sure my wine was still fresh (I waited 4 and it tasted perfect), the strong suction when I take it out says it all. I immediately ordered a second one.
