The rof's are nice but you probably cant shoot them all
good on battery
what do u expect from a gun meant to shoot tops of 7bps and you put a grip on that can do 15... you will chop balls if you use full auto at a high rof I suggest about a setting of 9-10 if you have a good hopper maybe even 12
Buy this, get a 12vlt or above and you will be impressed! I was!
