I was a strong lover of the Ys3m ball core, and after it broke after two long years I decided to try one of Moyu's newer releases. I bought this cube, and despite its drastically different feel from the Ys3m, I immediately realized its main potential.
Unlike other Moyu cubes, the v10 is light, airy, and hollow. The pieces do not carry as much momentum as Moyu's other releases, but its fast and airy feel made up for it. I could turn faster with less effort than other cubes that I've tried.
Out of the box, this cube is extremely dry and fast. It is also EXTREMELY loud. If you solve frequently in places like work or school, the v10's clacky sound will cause a disturbance to others. After setup, however, the cube becomes a lot smoother and less dry. The sound becomes a lot more muffled with lube, but it is still there.
After setup, this cube turns smooth and fast, and the new adjustment system is extremely intuitive and easy to use. I put several drops of Martian and a small sliver of weight 5 on the tracks, and I set both adjustment settings to 4. I found this setup to be the best, as it keeps the cube's natural speed while keeping it smooth and controllable.
The v10's corner cutting can be a bit difficult at 45 degrees on tighter settings, but the small cuts are almost effortless and completely unnoticeable in solves. Aggressive turning is not always accepted by this cube, however. I found that when I was turning hard, this cube catched a bit. However, lockups are very minor and infrequent, causing me to get amazing times on this cube with careful turning.
In all, the weilong v10 is an amazing release by Moyu, but its airy feel and loud noise may not be suitable for people who turn very hard. On the other hand, people who enjoy moderate-strength magnets and naturally fast cubes will find themselves extremely happy with this puzzle.
