My JJ Ceramic was sized perfectly for these. Progrssives great as well.
Very consistant for the price
Not very brittle
Shell isn't bright
These were only $45 for 2000 at Wal-Mart (and that's as cheapest by far in Canada). Wow, I was amazed at how great these were for the price. There were very few dimples, and they were small--definitely on par with anything by Draxxus/Diablo. The bore size was very close to perfect for barrels that don't have different bored backs (like my Ceramic). I would say 1/10 had a size or seam inconsistancy that affects accuracy, but thus far none have been too large to create a break (note: I operate at 500 psi). The fill very, very thick. I don't like this because although it prevents wiping, it doesn't create a large paint area. Fill in most other paintballs is designed to absorb in to prevent wiping, and I would rather see this. Also, the fill and shell are very dark, although some may view the shell being dark as a strength (hardy for the opposing players to see).
All in all, a great product. It has its weaknesses, but factoring in the price this scores a 9 on my scale any day. Some companies try to sell the same type product for twice as much. Zap is my favorite company to buy from for paintballs, thanks to products like this and the Spank series.
Not the best rec paintballs, in my opinion, but second only to the Spank series which Zap also creates (which can be purchased for $2 more per case, but is rare to find). Honestly, if small problems like the hard shell, dark fill, and rare inconsistancies were worked out, this would be tournament-grade paint.
