Old thread I know...I ordered these weights about 2 months ago, and after having to bore out the hole slightly, they work great.
However, for some reason I received another set of them in the mail about 2 weeks ago. I had not placed another order, so I called them up and left a message explaining that I'd received another set of the weights, and for them to call me back so I could arrange to send them back. 2 weeks have gone by, they have not charged me anything for the second set, and have not returned my call.
So, if anyone else is interested in a set, just PM me, and I'll send them to you. I think the shipping from Cali to Wisconsin was less than $10, so I'm not worried about getting any payment, but seems like someone should use these, otherwise they'll just end up in the junk.
