Blue are available also, but they only had white in stock at the time. You are right, one look at the chips and you can see they are clones, worse is there are many HK suppliers selling these chips either delibrately telling their customers they are original even though they know they are clones, or they dont even know they are clones, as not many people know DuoX 2 clones are on the market. So you may find some shops with clone stock and they honestly arent even aware they are clones. Easiest way to spot the clone is an extremely poor paint job on the PCB, soldering on the PCB is nowhere near as neat and clean as originals and the IC without any printing on it has been scratched down to remove its markings. Price well lets say a little more than Aladdin clones, and if you see anyone doing really amazing low prices on small quantities, then its a clone.
