They shoot accurately in a boomstick. (what paint doesn't?)
It does not shoot accurately with any other barrel. (okay, okay, I havn't tried every barrel) but most certaintly it won't fit in your barrel. This is a list of the barrel I have had no success with.
Stock spyder barrel
Smart Parts Progressive
ACI Graffiti (old style)
Another bad thing about these is that they are way expensive. I got 1250 for $30! thats about $60 for a case so that makes them about as expensive as Diablo.
I will never buy this paint again. I wrote this review in the hopes that, unless you have a boomstick and want overpriced paint, you won't either.
