The MoYu YJ GuanLong is a new, lightweight speed cube with a very low price point. It features pieces and mechanism similar to the YJ SuLong. Great as an inexpensive first speed cube for beginners! This is an amazing cube for beginners and intermediate level cubers. It is pretty fast but really controllable. With correct lubing, breaking in, and tensioning, it can cut 45 degrees easily, putting it up there with all of the great new cubes. This cube is designed for high-performance; it strikes a good balance between affordability and performance.
