The reason i got the new gaskets is because the syphon never worked in the first place, it leaked every time i tried to use it. no matter HOW tight i got the top on. when I screwed on the cartrigde, whoosh. all the charge shot out from under the cap. I changed gaskets, still didnt work. so i ordered replacement gaskets just in case BOTH the ones in the original box were bad. But eurkitchen failed to send them; after 14 days i got nothing but a worthess piece of metal.
