what did you do to it? cause if you suck at lubing and tensioning your cube might get bad lol. i have experience with that. my cubes are way better when all i do is a little bit of retensioning to make the tensions as even as possible without really changing them too much and just lube the pieces. if i do lube the core and completely retension it then my cubes suck. i think im one of the worst ever when it comes to setup cubes. maybe you are also not too good lol. but you said it came bad out of the box, in that case just retension it and lube it. and maybe change the springs but thats not really needed imo.
