Maybe Im the only one, but I can understand both sides to this issue.
For the Chinese manufacture, they are sitting on a Huge cash cow and want these cartos screwed onto every e-Cig in the world NOW. They are loosing tons of money everyday that the USA market does not have access to them. And since there is no such thing as Copyright or even Trademark enforcement in China, it is only a matter of weeks before another Chineses company is retooled and ready to flood the market with the same carto.
For the USA vendor, they dont feel the product is ready for retail. They feel that if they take delivery of these carto in the current design state, and under the current sales agreement, that they will not deliver what cartomizer users want. Then they will be stuck with a warehouse full of cartos they cant sell, a help desk staff that is loaded up with RMA requests and a tarnished name.
So its kinda a Catch-22 for both parties. And it is the Exclusive clause in the sales contract that causes it. Not the carto.
What is so disturbing to me, having dealt with Chinese suppliers for manufacturing tooling, is there constant and consistent lack of quality control. I am constantly amazed when a Chinese supplier will provide sub-standard products for review only to get furious when I would not issue a purchase order.
With the rush to market attitude and letting the end users be the beta testers, vendors set themselves up for failure.
I take my hat off to V4L for not exercising their exclusive contract seeing what they felt was a sub-standard Cartomizer. The reason I say this is not because I am a big V4L fan. In fact, I have never purchased anything from them.
No, the reason I praise them is because V4L lost the Potential to make a substantial amount of profits. It is harder and harder to find decision makers in a company who will turn down Potential for profits verses selling questionable quality products.
