Works great! Seals well. I read reviews of the vacuum systems vs. other more expensive tedious methods (inert gas, displacement floats, special decanters, etc.), and to my surprise, the vacuum versions worked among the best, if not the best overall. Of course, if you go with a vacuum capper, you gotta go with Vacu Vin! Just sayin.
