Love these jaws, they are well made, fit together well and will protect your work when you need it. The only thing stopping them from being a 5 star product is the weak magnets. They just aren't strong enough and therefore slip off when you need them to stay in place. So I took a chisel to the magnets (I wrapped them in tape first because they are very fragile and break into pieces - put on goggles) and then scraped off the residue and glue with a pick. These things are better than you thinkβ¦
