content: We have five SoSpenders inflatable PFDs model number 38APRO and ordered five rearming kits#0944 which state on the package that they fit the SoSpenders 38APRO PFD. The water sensitive bobbin in the kits does not fit the PFD and when we attempted to return the kits in the original packages to Amazon they would not accept them saying that they can not accept shipping of items that have gas in them. It is strange that they can ship to us items that have gas in it but we can not ship the same product in the original unopened package back to them. Now we are stuck with $120.00 worth of rearm kits that are of no use to us. Our recomendation is DO NOT USE AMAZON as they are a company that does not admit it has a miss labled or improperly packaged product.
