New Threaded Magfilter from CarrySpeed

I'm a bit annoyed at this. They probably conisdered doinga filter thread But i believe why they jumped on it right away was because people were doing diy to their CPL anyway.

I would contact CarrySpeed to see if they did a exchange but it cost me$20 postage to Australia to begin with!

I presume they are charging more for the filter adapter because why would people buy anything else from them filter wise afterwards?

guess I'll still be doing a diy with my CPL like millsart
