Optics Planet might be the worst vendor I have dealt with haven't given them business in atleast a decade. It's a sorry world sometimes and it definitely looks like someone swapped out the rings.
This summer I was changing oil and when I opened the oil filter I was surprised to find a used filter that someone had obviously returned. So for even a $5 oil filter people can be dirtbags.
Someone either knowingly returned the APA box with cheap rings, or the vendor selling through OP is selling those cheap rings advertised and boxed like APA rings.
Either way, it's an OP issue and not APA. They should issue you a full refund and return label. Otherwise simply submit a fraudulent charge notice with your cc.
This is insane! Wow! I have ordered from Optics Planet only a few times, but I'm keep this in mind if I ever consider it again.
I ordered my last set directly from APA, as they were cheaper than anybody else and had them in stock. They definitely don't look like those cheap Amazon rings.
