The biggest maker in Korea, their counterweight ZanNavi has made quite a name for itself. Shinwoo's greatest advantage is definitely its cost-performance. Taking the opinions of Korean players, Shinwoo's yo-yos are great performaners, but their simple materials and inexpensive manufacturing make the balance between price and performance extremely attractive. From simple looping yo-yos for beginners to off string models used by champions, to LED yo-yos, covering just about any need you may have. The low-edge Techno 2 is great for intermediate players. In 20100, Shinwoo even released their world-class full metal Zen series, making it a great choice for newcomers to metal.
