I'm thinking PBusardo's link is correct, and they are the vendor for UCT....
Not a vendor, a distributor....
A vendor is retail.
Goes like this: Manufacturer sells to a Distributor who sells to a Supplier who sells to a Vendor (Retail) or Wholesaler (like Health Cabin).
But not necessarily in that order for China.
Most (if not all?) Chinese e-cig makers don't actually make their own
devices, other factories do and they assemble them.
There are a few large ones (like
joyetech & Smoktech) who have their own dedicated factories, but most don't.
This is why you see
devices like the Vamo can be bought almost anywhere on Alibaba, because the actual factory that's making them isn't on Alibaba (or other sites like it) at all.
This is why finding UCT is gonna be difficult....and will require some connections in order to locate the actual factory.
