i PURCHASED THIS "STARTER kIT" TO RELEARN, AND ESP FOR THE GREEN BASKET, THAT I thought was useful and would cost me probably also about $ 11.00. This is a BALL product. What I found out was that Ball?keri (spelling) tops and rings can not be used with any other Mason jars. This is ok, if you know this. So when buying Mason jars, check what company makes them and buy the rings ect with it The package came also with info about Pint sizes and the more ornamental glass jars. Nice for gifts.
I am very happy with my purchase, I bought also a 4 Gal stock pot from Walmart that is also induction ready! My goal is to actually only can water for emergency uses, where first I boil the water, then can it. Should work. KW
I recommend this product.
