grannyj Smith The tattler rings are reusable and the rubber rings can be used over and over several times. You only have to replace them when they get stretched out and look worn. I have used them for years. They are expensive so I try to buy a couple of dozen about every other month. I have been using them for years now as they are different from using the one time medle lids. They are well worth having in your stock of SHTF items but you need to know how to use them the right way. If you decide to get some to try, then next time you are canning, only use them on a couple of jars and follow the directions to see how you like them and get used to using them. You would still use the same rings that you use on the other one time lids.
