According to FloorOne they are the sole distributers in the US.   I just put down 650 sq feet of 12mm Vectra.   It took me a while to understand the locking, but after I got that down it went pretty fast.  Only found 3 boards that were defective.  There are others brands that lock easier - don't know if a tight locking system is beneficial or not.   I just knew I wanted 12mm after talking to others who installed 7mm & 8mm.  This floor is solid and it looks really good.
