Ok what I have to say about something similar to monster balls well Impacts there kinda the same but impact are a bit better thenm monster balls but thats all I can say that is similar.
bt-4 combat with and electric barrel-hopper named VG (feedyourneed).
any electric hopper except the cheap ones.
Hitting people but sometimes they failed me but it was usefull most of the time.
Trees very hard to hit at trees and sometime players.
Ok I did use these they were not ok not the best I hated them hated!!!! my friends got in trouble because in most paintball feilds you can not use monster balls so what do I give this product 2/5 I gave it a 2 beacase I like the detail of the paintballs so thats my review.
I think I wasted my money saying that they are the best paintballs you can get. <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/it5RlCj3lmw&hl=en "></param><embed src="http://www.youtube.com/v/it5RlCj3lmw&hl=en&q uot; type="application/x-shockwave-flash" width="425" height="344"></embed></object>
