Some devices work with any kind of cork while some only works with one. You have to remember that corks such as synthetic, screw cap, agglomerate, Zork, champagne, regular, and vino-Lok are made of different kinds of materials and they are very much capable to damage your device if they are not compatible. Some of them could be considerately soft as they are made of recycled corks that are glued together while some could be very hard because their function is to make wines last for years.
