Query: Poor Quality

I've had my experience with these BB's (thankfully I wasn't the purchaser) and they are overwhelmingly junk. First of all .11 gram is outrageous. .20 is recommended for most guns, and usually nothing under that is even allowed in an arena (EX: Airsoft CQB Manassas). .12's are cheaper and usually made to save money and or for use in guns whose velocity would be very low with denser sizes. Whereas a .20 BB will safely pounce of it's target, .11's will probably shatter if shot anywhere over 250 FPS (300 is the velocity of a good gun) which can be very dangerous. It doesn't help that these BB's have seams on them, like plastic toy soldiers. Further reducing quality and accuracy.Long story short, DO NOT BUY.
