I bought this cube a few weeks ago, talking about it's quality it is super awesome it's very much smooth and easy turning and handling....best cube I ever had 😍😍
The cube itself is fast. Regular corner cutting isjust behind the first line and reverse corner cutting is past the first line, with the right tensioning. Corner cutting of the inner layer is also very good. I'm happy with the colour shades of the stickerless version.
The only downside of this cube is it pops sometimes when you turn fast.
I bought this cube around 2 months back when I averaged 4 mins. It motivated me to practice and I average around 1 min and 40 s.
So overall I would definitely recommend it of you are starting out and your turning speed is decent.
