Well a soon as I got home from the proshop i couldn't figure out why it was shooting like 1 ball per second but then I realized to turn the eye off. which took me forever to figure out. Otherwise I went through a hopper as fast as I could pull the trigger. shooting 16 balls per second feels pretty good letting rip. Also the menu system is kind of complex but just read the manual and you should be O.K.
If you have a cocker and are serious about paying 500$ and want to rip like never before GO FOR IT!
