I can't tell you how many California wineries have tried to sell me one of these gizmos. They push these gadgets pretty hard - I suspect more so because they are profitable rather than effective. I am highly suspicious of their effectiveness - I prefer the good old standby of patience.

There's a simpler option for dealing with corked wine - take it back. Most good wine shops will take back a corked bottle and swap it for a new one. Unfortunately, I can't say the same for big-box liquor stores and supermarkets.
