Query: doesn't do much

I got this at a grocery store thinking it would be great since I only drink a little bit of wine or sake at a time.I ended up giving it away to goodwill after a few months because it doesn't really help the wine or sake (at least not for weeks like I'm prone to need between glasses) and it is annoying to use the plastic thingy, trying to get it tight and worrying that you're going to break the bottle.I think a nice reusable cork kind of gadget would do just as good a job, take up less drawer space, and look prettier in the bottle.
