So I'm having a set of attenuated SPL plugs made by ACS Customs. I called them today to get an update. Also, I wanted to ask them if they're able to send my impressions back with my order when it ships. Reason being, will prob have a set of CIEMS made later this fall. The guy the phone said no, they won't release them. However, they will keep them on file for 4 years. He said if I like, I can purchase a duplicate mold for $10. Serioulsy!!! Why don't they make a copy for their records and send me back my original molds. The molds I sent are not their property. I don't know why they feel they have proprietary rights to my ear molds. What the heck!! This torques me. Is this common?
