Amazon Customer 2 Great buy! I got them to supplement the weight set I already own, but I like them so much, I'm using them exclusively now. I previously had chrome plated ones plates that had rusted with the chrome starting to peel. So now, I put away my older plates and am using this new, rubber coated set all the time.I'll probably purchase heavier plates in the future, but for now, this is more than enough. The collar fastener, which spin very nicely on the bar shafts, even fit on my older barbell (which is missing a collar). So I got lucky with that, too. I highly recommend this set.
