Not as advertised
0 von 3 finden das hilfreich After ball has reached max spin rate, you do not get an even line on ball. When pen is placed in slot, ball is then mis aligned and smudged line remains. If you lightened up on pen then a few dots appear and you have to put a heavier line on ball. I just do not think it is worth the money.
