Quoted from Gnatty:
Anyone else getting about 75% rejects into the toy box to lock a ball? Mine goes left and out 3 out of 4 times at least.
It's not the diverter adjustment, you want to set the right hole eject power back. Go to adjustments and set it at 200. Mine was 220 and had same problem. Now only occasionally it over shoots. Going to fine tune later.
