Break well on impact
Fill is very oily and stains clothes
These are the paintballs my local paintball field uses. For the most part, I've had pretty good experiences with these balls. They work well in my Spyder Classic with a SmartParts barrel. The first time I used Formula 13s, I did have a few break in my gun, but I think it was because of the gun itself and not the paint. The balls shoot nice and straight, usually break well on impact, and have a bright and easily visible fill. They seem to have a long shelf life too which is nice. I have some of these balls left over from last winter and they still perform well a year later and hold their shape. The only complaints I have about these balls is that the paint is very oily and does stain clothes if not washed off right away. They also smell pretty bad.
Overall, I was satisfied with these balls and would recomend them for their performance and long lifespan. Personally, I do perfer R.P. Shearer paint over these, but they do their job
