I have personal experience using these lids! I have had 100% success with them sealing. No more running out to the store for more lids, once you have a full stock you will never again be in a panic. They are easy to use and store. I am planning a class to teach the art of home canning so this is a perfect complement.
Here is a bit from their website:
TATTLER Reusable Canning Lids were developed to fill a need for a reusable home canning jar lid. It does everything it is claimed to. We guarantee the TATTLER plastic lid to last a lifetime or we will replace it free. However, no customer has EVER made the request to replace a single lid.
TATTLER lids work in any accepted method of use, pressure cooker, boiler, etc. and they come with a rubber ring which is also re-usable, so long as it is not damaged (cut or stretched).
TATTLER lids are especially desirable for acid foods, pickles, peppers, tomatoes etc., since they will not corrode. We have only recently disposed of product that was canned over 20 years ago and they were still tightly sealed. (We did not and do not recommend use of food with extended age, this was only furnished as interesting info.)
TATTLER Reusable Canning Lids are exactly what we claim them to be, “REUSABLE!” Many of our customers have contacted us and told of more than 30 years use. I welcome you to visit our testimonial page and see for yourself.
The reusable nature of TATTLER lids is perfect for the home canner interested in saving money and time. They are also fantastic for those of us who wish to Reduce, Reuse and Recycle. TATTLER Reusable Canning Lids fill a market need by providing a cost effective alternative to metal lids, as well as a safe, environmentally friendly product for your home food preservation. One very important factor regarding TATTLER lids is they are BPA FREE!
