This stuff is just bad. Quality ranges from being extremely squishy to hard as a rock. Anywhere from 30%-90% (Yes, 90%. That's not a typo) of your ammo will be unusable and will need to be sorted out of rotation. Even when that's done, the remaining ammo will still have feeding issues. I've seen this ammo jam in every single blaster it's been used in including modified 3S Perses. Blasters with internal magazines are particularly susceptible to jamming or not being able to shoot this ammo even when upgraded with a K25 or K26 spring. I cannot stress enough how bad this ammo is. If you're looking for ammo for night or glow light play, you're better off finding a white ammo alternative that doesn't glow but is still visible (OutofDarts White Proton Rounds work great). This stuff just isn't worth it.
