Reusable Canning Jar Lids - Update

 Gearing up for canning season, I came across this link promoting BPA free reusable canning lids.  This product has been around for quite a long time ... just wondering if you have heard about said lids?  Here's a link to the Tattler Reusable Canning Lids ... and the Homestead Revival blog that has a drawing to give some away.  I entered the drawing ... and am seriously thinking about making a purchase.  If you have experience with Tattler lids, leave a comment.  Thanks

Update:  Maria asked a good question about whether or not the rubber seals are reusable .. here's what the Tattler Faq/Testimonial part of their website says: 

Q:  Are the rubber gaskets reusable, and how long will they last?

A:  Yes, the rubber gaskets are reusable and will seal numerous times when used as directed.  When cared for properly, many years of use may be expected.  Testimonials from our satisfied customers report use of rubber rings for more than 20 years!
