I have tried a few Vevor tools and haven’t been let down yet.. I have seen a few complaints about the product that I don’t believe is the products fault.. 1st off any type of screw press should be greased/ lubed at the threads and the swivel to prevent binding.. as for ball joint removal.. make sure ur work surface is clean.. add heat to ball joint before trying to remove.. If you take these steps the product will work fine.. If u just take it out of the box and throw it right on a ball joint that hasn’t been removed in 30 years then any product could break and or give u problems.. That is just plain old user error..
