Don't repeat our mistake. I figured since these pliers are more expensive and heavier they would do a better job. They require a person to get behind each J-clamp with pliers to tighten them. I'm not saying they twist the clip a little loose. It's nowhere near when these tongs will be done with it. I would find them useless. The cheapest of the cheapest beats the results. I posted photos. Save yourself the hassle. Hope this helps someone.
