The pliers themselves are too thick and strong to fail. They are strong and do what they are supposed to do. I used them this past weekend of January 21 to castrate, mark and vaccinate a group of 400lb calves. They work as they should, but the chain and thin little ring at the end have the typical Chinese quality you would expect. The ring broke immediately when he was hung from the slide with his calves held upside down. The chain did hold the tongs, but it's the same thickness and quality you would use to tie a Chihuahua to the steps in front of the toilet. The tongs themselves = GoodChain and the ring = a step above Lego plastic.
