In my opinion, this is probably the best 4x4 on the market. It is very light, which I appreciate for longer sessions. The turning on inner and outer layers is very smooth, and required minimal setup before it started performing to my liking. Definitely recommend this.

its op
i broke my pbs without setting it up
outers feel like a moyu 3x3
inners are kinda strong, so glad i didn't buy the triple track
if you like moyu 3x3s and like a good 4x4 stability buy this one
KEEP IN MIND: this is coming from someone who upgraded from a qiyi qiyuan 4x4 (it sucks)

That’s all I have to say, also get benmajin

Came pretty dry out of the box but still better than both the vin and mgc. Much smaller than both cubes. Once setup, instantly dropped my global from 34 to 32.

This is my first 4x4, after waiting a little time and a few reviews (and a great sale!) I got dual track/ball-core version. Out of the box the inner layers felt tight and sticky while the outer layers were light and fast. After setting tensions and overall tightening a little bit I gave it a bit of a “Yoo” lube set up and used weight 5 and Dignitas to smooth it out and used Mystic and DNM-37 on the inner layers to speed them up and over all this has balanced the cube out nicely! Crispy turns that are nice and soft. This cube is AMAZING! And has given me a new love of 4x4 cubing!

I was able to use this cube like it was a three by three really well, by just turning the outer layers. It felt very fast, and extremely stable. However, the middle layers for me seemed to have a harsh click that made it feel almost a bit sluggish to turn. But over time, the click seemed to lighten up, and now I have a overall good four by four. The UV coating is nice and shiny, and overall, besides the strong magnets in the center, it turns very fast. If anything, those magnets give it more stability. But if you do not like strong magnets, you may not like this cube.
