As a home canner, I’m a little leery, I prefer new and sterilized.
You are probably a bit like me. I was taught to sterilize, sterilize, sterilize. If you don’t can properly, you can injure/kill someone who eats the food. Have any freepers used this product and can they attest to the fact that it is just as safe. I am not saying I won’t use a new product but I have been taught to take safety precautions seriously.
