DaYan TengYun V2 3x3 Magnetic is a very exciting release! DaYan used to be known for their world-class speedcubes so seeing them integrate new technology and designs to their speedcubes is fantastic (just like the performance)! What is cool about the TengYun V2 is that you can adjust the core elasticity and spring compression just by using the included tool. Easy! If you are a fan of the buttery smooth turning found in the GuHong V3, you will want to give this a try!
