    "These are so fun! Great for cqb! Also fun to pull pranks with! I wish you didnít have to modify them to make them go off faster. Stock they take any where from 8-10 second to go off.. the striker doesnít put a big hole in co2 so it seems to take forever to go off. But still fun!

    "cool but the ones with the caps on either side are not because you always loose the caps. but you can just buy the regular ones as well. PAINT THEM OGANGE BEFORE PLAYING W THEM! BOTTLES TOO. People steal em off the ground like no other and they are hard to find so you just never know.

    "Work great no problems except for the fact that on mine I need to pull the striker back after pulling the pin out to get enough force to puncture the co2 canister inside.
