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

"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.
