These collars look good and lock tight on the barbell. The only problem is that the magnets are not overly strong. I don’t want to have to pry them off my rack but when I try to atick them on the rack they slide down. Not a big show stopper and I debated dropping a star but they are better than standard collars. Not sure they were worth the high cost though.
