I have owned a Zyliss vise for years and have loved it. I am 6’5, 300 lbs and have put my full weight on it tightening things, never a problem. BUT. . . recently my brother bought one at a show. He paid about $250 for it and was all happy. Of course we put it to the test and sure enough, I broke one of the vise jaws right off the bat. When we looked it over some things were very obvious. The jaws were NOT the original casting material. My brother called and sure enough, they admitted that the newer versions were cast over in the far east somewhere. They did make it good though, they had 22 of the older versions left and charged him an additional $50 bucks for one of them.
So, word to the wise, if you think the zyliss vise deal is too good to be true, you are right, it is.
I hate it when some marketing type just has to make things more ‘profitable’ by cheapening them up. Sure, more sales, for a little while.
