I honestly can't think of a bad thing to say about these plates. Accurate, won't chip your sleeves, can't ever fall apart, all the appropriate colors and cheaper than any of the plates offered by the competition. They do come with a little grease from the factory, but just take some paper towels to them for a few minutes to get the worst of it off and you'll be good after a few days of use. Quality product from Vulcan, for sure. Unless you are holding USAW or IWF sanctioned meets and have to have certified plates you really have no reason to buy anything else. Perfection.
