So, My friend just got one of these things so i thought id go check it out. I disassembled the gun thinking that at least the board would be different. nope. Although it does have a better firing chamber and solenoid then the ion. So the next sunday we decided to go try it out on the field. I was surprised at how well it worked completely stock, even when the stock insert was a little big for the paint we were using, it was still really accurate. The only thing i really dont like about this gun is the weight, i thought SP would make the epiph lighter then the ion but is certainly heavier. Better balenced, but heavier then the ion.
Conclusion:
If you need a back-up or are a beginner to intermediate player, pick on of these up, they are worth it.
