I've had my Wise for about 7 years now not really sure exactly when I got it. Crank stringer can be very accurate it all depends on which one you get. You should be able to string a racket in 30 easy with a good crank. Much faster if you try.
Everyone has the right to be stupid... it's just that some people abuse the privilege...
