Because if they scammed people by selling lm561b for lm561c s6.. then what else do they lie about.. you buy lm301b and they may ship you cheap chinese led.. you will only find out after testing them because they will be looking exactly the same.. and as a I said.. alibaba is a chinese platform and by no mean do they care about international buyer.. alibaba is also not aimed at consumer (ali express is) it aims at retail so they couldnt care less about what individual order for themself.. just think that mars hydro is still selling a shit ton of their blurple light been called on them over and over with their false claim that 1000w mars hydro does match a 1000w hps while using 50% less power.. all real bullshit they are still in business today and selling a tons of their light to uneducated consumers..
My advice to you is you know they are scammer while you can take a chance with another seller who could be one as well but there is a chance they are not.. few people bought from meiju including myself and are satisfied but maybe they shipped me good units hoping I order more than send me the fake one.. who knows but your money your problem
hope you keep us updated whatever you decide
