I have a Klipper and have done probably 50 stringjobs on it so far. Love it.
1) It can be difficult stringing an EXO3 Prince racquet with it, given that it is just two clamps. It can be done, but is not easy.
2) After about 15 stringjobs, one of the clamps became useless. I replaced with a Gamma clamp. Other people have noted that the clamps are fantastic, so perhaps I was unlucky.
I am very very pleased with my purchase, and have not even considered a higher end stringer. It is accurate and simple to use.
5.0 game with 2.0 consistency.
