I had a problem when I ordered my PP502's from Charlie (KERMA) but it turned out that they were held up by the dumba$$es in Canada Customs because there was "insufficient information in the description of the parts". When I called Charlie about it, he said he'd be glad to send me another set of nozzles and then I could just refuse the delivery and they'd be sent back to him, which is what I did. At first, when we couldn't find the package, he was willing to send out a second set free of charge until the first one's either showed up and I sent them back or they got returned to him. He's definitely a good person to deal with and is very straight-up with his dealings. If there's a problem I'm sure he'll get it straightened out with you. On a side note, the nozzles are definitely worth the wait!
