Hi All!
I never tested MB, the cause is really simple: i will not pay the same or higher price for something, which has obviusly much-much less quality (I saw the pieces) than Lego. But trully, even Sluban products have better feel for me and my hands.
Generally to clone brands: i tested now couple of them: Oxford - perfect, Sluban - OK, Enlighteen - quite ok, BanBao - no way...i sent it back and traded for Sluban. I have no problem to use "alien" or even modded parts, if the design wins with it.
Honestly we all here, who keens on Lego, we do well. Our life is good, we can satisfy ourselves with such premium products. Meanwhile i built my Sluban sets, i thought, that: i don't care about patents, and argues about what is real and what not, it is a toy. What does impress us in Lego? The building experience, to create something, to put our visions into reality. I think it is really good, that a LOT of children can experience this great feeling, altough they or their parents could never afford Lego - i know what i am talking about... In this point of view i do believe in clone brands: maybe they are not another shitty plastic pieces, but smiles on children faces. Do not take anything too serious!
I will not start a debate here, i just told my opinion. And I play Lego.
