I have used agitators and borrowed a halo and an empire
Ion, ndz trigger, cp asa, redz clamping feed neck, j&j s2 14" barrel, fasta loader, lock lid pods
have not broken a ball because of the hopper yet
large ball capacity
The force on the ball stack can push balls past the detents
The first thing i noticed was that after high rates of fire the force of the loader would shove a ball into my stock detents so there would be one and a half balls in the breach. This problem was easily solved by replacing the stock detents with killa detents and never had a problem yet. The orientation of the lid has not caused a single problem all though some people complain about it. i didn't know i could walk my trigger so fast until i got this hopper and its cheaper than a halo or empire. as far as the led version the game timer and low bat indicator was not worth the extra ten dollars or so.
If you are a player on a budget this is the hopper for you good rates of fire and it doesn't sit very high off the gun either and the capacity is a plus for those of us who go through a lot of paint.
