The ball !!!!! Excellent at all points. A course can not use with a right arm, you would not do the reading but burning over time, choose the right arm OM series (the same arms straight) If I use them on and MK2 Technics Numark TTX-01 (with the arm S) It works with the fire of God, it is the groove like a train into the rail!! I think the price is very decent for this level of variety! The only drawback is I would say, the tip of the needle is said fluorescent, neon never!! But a pure c detail that is useless!! M'enfin Good Buy if you do not. If you have better, Well, Well good for you.
See you soon guys !!!!!
