Query: Steer clear of the Rubik's brand Rubik's cube!

If you are at all familiar with the larger rubik's cube, then it is no real shocker that the Rubik's brand is not the best option. These cubes are pretty expensive, but very poorly made. It is prone to break easily, but even if it doesn't, the motion is not smooth at all. The stickers will wear out with a solid week's worth of play.Your best bet is to track down an Eastsheen cube (best bet is on eBay) or to wait for V-cubes to release their version.If you are already stuck with one though, replace the stickers at [...] and browse online for a cube-lube (again, eBay is a pretty reliable source), or even just a silicone-based lubricant. That ought to get you some decent use out of it.
