you have to remember,its all about the vacuum.
i always keep about 9 or10 ce3s thread side down in a plastic pill bottle,waiting for use and this way i can tell if they have a leak,i have some paper towel mashed up in the bottom of bottle to soak juice if it does leak.
i have found that as long as you draw the excess air out,i don't have any leaks,,they some times set for several days and not a drop of leaking.
