My son (13 years) ordered this with birthday money, despite having about 15 other nerf guns between him & his brothers. This one even impressed me. It is powerful, and the bullets shoot out in a blare. It is not noisy like the machine gun havock. The bullets when hitting the other side of the door which I am behind actually sound like the children are throwing toy cars at the door. If a bullet fired from it hits you in the face then it hurts. It has ten blue darts with in but also takes the plain orange ones but NOT the black rubber tipped darts (whistler ones), these ones jam. You need to close the little shutter on the top of the gun for it to fire. It has a turning cartridge so you load 6 darts then turn it and load the other 4. If your children like nerf this is a good present. Any boy who likes guns will love this and it is really good value for money. He paid £15. Both my husband and I are impressed despite the forever nerf gun wars that go on at our house. It is light enough to take on a 6 mile trek in the woods, which my sons & there friends do with there guns. It's nerf or nothing, the children keep telling us.
