In january of 2006 i purchased a pair of Mares Avanti Quatro Excel fins from Scubastore - Diving Gear and Dive Equipment, Diveinn i never used the fins until October 2006, now approximetly 100 dives later they are starting to fall apart, Whats happening is the opaque plastic insert on the fin part is coming away from the fin, now if it was just the one fin i wouldnt be too concerned, however its both fins and the problem is identical on each fin (looks like they havent been glued properly in Manufacturing) obviously the fins were quite expensive and i expect much more than 100 dives from them, What course of action can i take (if any) to be sent a replacement pair, thanks
