Review on Air Cork Wine Preserver (Burgundy): Save Red and White Wine, Reusable Stopper, as Featured on Shark Tank by Daphne Henry

Just received was very impressed with the whole idea. However, over the past few days, the balloon has deflated very quickly on its own several times. That's too bad, I wouldn't trust it to seal a bottle of wine lying on its side in my wine cooler (unlike some other wine vacuum kits I've had). I can understand the slow deflation but it was overnight. I'll give him a few more days, but if he can't stand the pressure I'll send him back. Update - I replaced the canister with one of the others in the pack and that seems to have fixed the issue. I was pleasantly surprised to receive an email from a company offering a full replacement based on that initial review. Not necessary in my case, but impressive customer service!
