the cube comes out of the box very sandy, but that goes away with breaking in. the overall feeling is strange, it feels like it really needs magnets, its not bad but a little unstable, after overlubing it with slick lube and putting it on mildly tight tensions, there is also this annoying spring noise that won;t go away no matter how many times i lube the screws, but over all it pretty good but it won't become my main over the thunderclap M though.
