Selling used WISE2086 electric tensioner: http://www.tennishead.com/ Used for 1.5 years. Still works great but I wanted to get the newer model which allows for specifying tensions lower than 20 lbs. *** Has only been used for badminton with a max tension used of 33lbs *** Selling for $400 (new one cost $545 now - spoke with Herb Wise himself to confirm pricing). Available for pick up only. Please email me at trinhity [a] gmail.com
