This is the smoothest cube I have now, its corner-cutting is great, and it never popped since I bought it. I dont think it needs lube. Because it is a good cube alone.

No corner twist
It has never popped on me
it was a great first speed cube to me
make sure you lube it with either heavy or medium lube

I bought this cube in 2015, at the time it was a great cube, an instant main, however now with the new 3x3's out there it simply isn't worth it anymore. The cube is hard to tension, if you tighten it too much it becomes too slow (but still pops) and if you loosen it too much it's too loose and keeps poping. The cube is also extremely loud, but has a good feeling. I would highly consider getting something else like the valk 3 or the gts2 since they are far superior than this cube.

My MoYu HuaLong (I bought it off amazon, but this looks like the same thing) was really great, but there was 1 problem, when my corner piece popped, it fell on the ground, and broke into 3, and I couldn't put it back together, it still worked though, but when I try to corner cut, sometimes an edge piece and a corner piece will pop out, otherwise, it is a great cube.

This cube is the best cube i had before my Valk.

This is a cube that I pick up quite often

Very smooth and fast. Extremely crunchy and moderately stable. Corner twists and pops occasionally (on my loose tensions). Overall good cube and would recommend.

I got his cube at christmas and it is pretty good. I initially ordered it because of the apparent 60 degree corner cutting after loosening the tensions it managed to achieve 60 degree corner cutting but popped very often after re tightening some sides achieve slightly over 45 and some just under. This is great tho and turns extremely well. The reverse corner cutting is also pretty good and achieves half to 3/4 of a cubie of cutting.

This cube is a great cube out of the box. It is a little loose, however it turns fast and sounds crispy. It does pop a little, but after making it slightly tighter, this cube is phenomenal. It quickly became my new main.

I love this cube, I have had it for over a year and broke my pb's with it, i got 15 seconds within one year. Overall the cube is really smooth with 45 degree corner cutting and I love this cube.
