Cool shape, reliability, blast radius. It worked when I through it ( you need to throw it at a high lob so it comes down on the are ), it threw paint around a 15 foot radius.
The color, i got milky white ( all they had ), it is kind of a crappy color, could barely see it. The grenade's firing last only 2 seconds, then its done. Didn't really cover the whole area, but good enought.
Good for the price, easy to use, and a hell of a lot better than the tippmann's grenade ( crap ), so pick a few up for the hell of it. Should work good in speed ball or close open woods games.
