This is a portable badminton stringing machine. It can be fixed to a desk or other surface, and you can apply tension by simply pressing a button after securing the racket. I always string at 32 pounds, and I can finish stringing without any problems. Operation has been confirmed, and because it's a machine stringer, you can string at higher tensions and more evenly than with hand stringing. This machine has passed the certification of the Asian Badminton Confederation. I will also include the nipper pliers and awl that I used to pull the string.
