I purchased the rubber-coated olympic weight plates. They have been outstanding for use so far and I like the rubber coating on them as they don't "clank" when using. Very solid and good value for the dollar - nice that shipping is included. Would definitely buy again, but caveat (and probably true for everything that is rubber coated) - you may need to air out the items for a day or two in sunlight so the "new" gasses can appropriately dissipate. This is not Vulcan's problem - it's just normal for anything that is made of rubber. Once that's done, it's good to go. Just wish stock would come sooner - it took a few months to get the items. Again, not Vulcan's fault - just another by-product of life during a pandemic. They were great about keeping me posted on the progress of the order, though!
