For all those who complain that this cube "breaks". A cube does not break it "POP". These cubes are adjustable, which means that they can be assembled and disassembled. Yes, my cube in Pope after 1 minute with an algorithm I use to pay my cubes. For those who are unaware, the part of the center of each color has a cap which hides a screw. It can even tighten or loosen your cube. POP so that more or less. After adjustment of mine, no worries, no more POPs. it will take about 5 minutes. You'll just need a Phillips screwdriver.
Otherwise, getting back to the cube, perfect for speedcubing. the algorithms to spend alone after moving all sides for a few minutes. Lighter than Lunhui. I even think that for some, the lubricant is optional. Delivered on time, with additional stickers and a small bag for my part. It's always nice.
I prefer my other Zhanchi Purple much more fluid, and above all, the colors are simply much easier to distinguish. If you want to do speedcubing, go on white or black. Avoid purple, pink, blue etc. Or take the stickers that come with it.
Defects ... only to find a fault stops and corners are not necessarily fully assembled. But hey ... just the Do It Yourself, this is not the sea to drink. Otherwise I would have taken a "Do It Yourself"
I can not find him real fault current. Very Satisfied. You can go. By cons, be patient, it comes from afar.
