One the more sought after and safer airsoft grenades gets the attention of Matt in this EvikeTV episode... "Add the Tornado Impact to your arsenal of Tornado Timer Grenades. The Impact grenade explodes on impact, compared to the Timer grenade that offers set back times of 1.5 or 3 seconds. The Impact Tornado explodes immediately once it hits a hard surface - from as little as one inch away on concrete, but will hold - even with the pin pulled - when you shake it aggressively in your hand!"
