Pre-ordered from Speedcubeshop on 15 November. The first batch had mold defects, so Speedcubeshop sent them back to QiYi in exchange for non-defective cubes. I've been waiting
patiently impatiently for it ever since.
Okay, so my Wuque arrived Tuesday. Since then, I've been absent from the world, laying in a puddle of my own drool with a stupid grin on my face and this amazing puzzle in my hands.
tl;dr
Get the stickerless Wuque, it's amazing.
I have fallen in love. This cube is more than a good cube, it calms my angry soul! I've been so frustrated with the catches, lock ups, pops, lack of corner cutting, from 4x4's these days, ugh! This cube eases my frustrations and solves ALL those problems.
I've seen every YouTube video to date with the word "Wuque" in it... All of them. And I have noticed that a ton of people who got the black Wuque said it is sandy, a little sluggish, and I noticed that the cube sounds clacky and stiff in the videos. They say it's good, but nothing special. Everyone (and I mean everyone) who gets the stickerless Wuque says it's smooth and fast, and is totally blown away by it. I noticed that the stickerless ones sound swishy and papery...(not sandpapery, like the black). The stickerless sounds smoother and more buttery.
Side note: Every cube I have tried, regardless of brand, has felt much better in stickerless than in black. It's the plastic. Even my beloved black Yuexiao isn't as good as my stickerless Yuexiao, or my wife's stickerless Yuexiao... no matter what I do to it, the stickerless is always better.
In regards to the mold defects, other cube shops say that as long as you break in the cube, the mold issues are not a problem. I ordered from Speedcubeshop and they ensured that none of their customers got the chance to find out what an inferior product felt like. I've had cubes with that kind of mold defect and it DOES affect performance, no matter what QiYi says on their Facebook. To anyone who got the first batch and found mold issues, I'm sorry you wasted your money. (QiYi has said on their Facebook to talk to your cube shop about an exchange.)
The day I got mine, I took it all apart and carefully inspected every piece. No mold defects. No defects at all, just like the name. ("Wuque" means "absent of flaws/imperfection.")
The stability is fantastic, corner cutting is amazing. It is fast and controllable. Just like people say, it feels like a 4x4 version of a Valk. And my internal pieces are YELLOW!

(What color are your internals? I've seen orange, blue, white, and i think green. I've heard of red, too.)
Con: it's 62mm, and I think that 60mm wouldve been better. (Wow. I'm complaining about 2mm.)
