Thunder B Airsoft Co2 Simulation Grenade (Package: 3 Shell Set / Flashbang)

"These are loud. Yes, the shell ruptures... that's what causes the noise. I can throw these 40 to 50 yards and the timing is perfect. They go off almost immediately after hitting the ground. Should probably "cook it" for a couple of seconds before tossing through a portal.

Cons: The pineapple shell is way too large to fit into a frag grenade pouch.

"Do the Shells break after one use? Because if not this would be a definate buy for me and my friends to use during our neiborhood games.

"I just got one of these and tried to use it yesterday. It took 4 tries to get it to go off the first time The second time, I dropped it with the pin still in and then picked it up and it went off in my hand. Luckily, I'm ok. Yes they're cheap and they're reasonably loud, but don't trust them.

"Bought it, used it, broke. Got replacement, used it, broke. Used my buddy's new one, and it broke. I swear, these are made of the cheapest metals around and just destroy themselves after one use.
