I have not heard of this new device, but I have heard of the plastic bag trick. For those of you who have experienced corked wine and are interested in the plastic bag trick, be aware of the oxidation that takes place when you leave the bottle overnight. If you can't or don't want to return the bottle for some reason and the wine can not be exposed to that much oxidation over night because either it is too old or it is just not meant to be aged, I suggest that you pour the whole bottle into a ziploc bag and leave it in there for an hour or more. So your friends don't see you pouring your bag wine, you can always pour it back into the bottle.
