Thank you for that info!I used some of those last Fall and they’re Chinese made junk. 60 percent failure at least and lots of buckling. Look at the reviews and you’ll see others with the same issue. Would not recommend these or the other ones from Chinese sellers.
I just threw mine in the cabinet. No idea that there was junk out there. I have always bought Ball brand on sale or end of season clearance. Normally from Menards or Kroger.
