Anybody use these? Reviews?
There was a positive article on them in the march/April 2011 edition of Countryside magazine. Bonus: they are BPA free which is more than can be said of both the Ball and Kerr lids.
They’re $278 for 500 lids with rubber rings, or 55.6 cents each. Big Lots has “Golden Harvest” Lids at $0.99 per dozen, or 8.25 cents each. I can about 500 pints a year, so I wouldn’t break even for 6.7 years. I guess you have to weigh the fact that they’re BPA free. The seal along the edge of the lid contains BPA. Probably the risk is minimal since the jars are stored upright and food content is not in prolonged exposure to the rim of the jar. I’m more concerned about hard plastic bottles such as Orange Juice Containers, where the liquid is in constant contact with BPA. Almost every aluminum soda can is coated on the inside to control corrosion, and the coating contains BPA, as well as most canned goods. Almost all Bottled Water containers contain BPA. People think it’s healthier than filtered tap water… yeah right. Evian spelled backwards is Naive.
Although I have not used them before, I am going to get some of these this year for my canning. My thought is more so towards the re-usability aspect than the chemicals per se, because as hotwired mentioned, you can’t really get away from it everywhere, but certainly it’s a side benefit. My volume will be fairly small, but I will recoup the cost some by selling the lids that come with my canning jars – I have yet to buy thos.
Anyhow, I found an article from the American Home Canning website to be the most helpful.
Also, from everything I’ve read you really have to pay attention to the tightening, as it differs from typical lids.
