Now i have not given this cube a proper set up, so this may or may not be a false review, but im doubtful cleaning it out and lubing the core will magically make it world class or better than the mgc. its pretty fast and has particularly fast and nice feeling inner layers, and the outer layers are nice as well. it has pretty mid-not too good cornercutting which is very noticeable when switching between this and the mgc. i also strongly dislike the shades. this cube pairs great with martian while i primarily use lunar in my mgc. Now i wouldnt NOT reccomend it, because its still a great puzzle for a great price, but the mgc is simply a better version of this for the same price. nice to see shengshou getting back in the game though.
