1. Extremely light and compact.
2. Unbelievebale consistency and flow rate.
3. On/off valve switch included(a detail forgotten on some high end HPA systems).
4. Extremely fast recharge rate! (I had a friend rip a bunch of balls on my Sandridge as I watched the gauge, and the gauge needle was bouncing back up to the set pressure very fast>
Weaknesses:
??????
Conclusion:
Quite possibly the best system I've ever used. It's compact and light and performs extremely well. They are alot cheaper that the Max Attacks when they first came out. The flow rate and consistency is extremely useful when shooting alot of the high end guns with high rates of fire.
