Have been using them for a couple months and they are great. No complaints here.Product was exactly what I wanted and arrived quickly.I ordered these knowing that a few people had a missing plate, so I knew I might have to contact the seller. BUT after ordering I see why this happens. I got my weights in 3 separate boxes one box being a day late. Im not upset by this and they're great weights, just wish the tracking on the customer side would say that its multiple boxes. Again, fantastic weights and helpful/responsive seller :DI bought these on Prime Day along with quiet a bit of other fitness equipment. They are pretty good quality, especially for the money. I wanted them because they are slightly larger in diameter than standard plates. That allows me to load the bar much easier while not using a deadlift jack. A bonus is the plastic/urethane outer coating protects the floor.I wanted to use them for a few months before leaving a review.1) Plates shipped separately by weight. Of all the gym equipment I've ordered, the plates came through properly packaged to ensure there was no damage to the product.2) The weights are accurate. The rubber compound is rugged. The metal insert perfectly fits an Olympic style lifting bar. The 45 lbs plates are thick, but this is expected for a bumper plate.3) There is a rubber smell to them, but I lift in my garage & I don't have an overly sensitive nose. So I consider this a non-issue.4) After approximately four months of daily use, the weights hold up well with limited wear. I was concerned that the metal inserts would dislodge with exercises like deadlifts, but that is not an issue. I have only noticed a small tear on one of the 25 lbs plates. A small piece of rubber tearing away from the plate. However, it is small, an does not effect the weight or efficacy of the plate to any notable degree.5) There is limited bounce on the rubber, so you don't have to worry about a weight or the bar bouncing high back on you in the completion of a lift.Overall, good plates for the money, that are perfect for deadlifts or instances where I fail in a lift.- EThese weights are great for the price. I have bought a few of the seller's products and am happy with my purchase.Weight was exact. Quality is good for the price. Shipping was fast!These bumper plates are nice. They weight out correctly and they are well built. Only issue is they're a little on the large side. They're about and inch more around than my other plates and about a half inch wider. So on my hex bar I should be able to get 405 on it easily, but if I use just these plates I'd only get 315 on them tops. Now I'm no longer deadlifting really heavy weights and the fact that they stand taller gets my lifts out of the range that's bad on my back so doesn't really matter to me. But to others that might mean something
