Deffinately the best reusable grenade you're going to come across for airsoft, I have the red which makes this easy to find after a match as always I'd suggest writing your initials on the grenade itself. The device is completely reusable and can use green-gas or propane. If your opposing team is caught off guard this device can be a game changer. CQB is the best environment for a grenade like this with many walls and hard surface areas to discharge against.
Talk with your game masters about the rules for grenades before purchasing this, some folks don't like grenades as they take the fun out for some players who don't have $100 for a grenade and it can make your games one sided. IF you have a team, I suggest every member carries at least one.
Gas Release Valve so it can't be overfilled
Uses Green Gas or Propane
Spins on impact for maximum effectiveness
Bright colors to be easily found after a match
Eats ammo - Don't waste this on an empty room
Eats gas - ^
Takes a lot of time (5+ minutes for the inexperienced) to prep in a rapid game environment you may have to let it sit between games.
