I have had my Wise 2086 Electronic tension head for over 10 Years, It has only failed once in that time but has completed 10 of hundred's string "pulls" !

These free up the stringing area, no blocked holes and hold the racket in place better that the original supports

This is so simple yet can save so much time and hassle on Shared holes.
Buy a good one and it will last for years!
