Well my friend came over wit his reloader B and we decided to test it out.
Turning it on is super easy. Just press the button. Same with turning it off.
It kept up very easily in semi mode, going around 15 BPS.
Kept up very easily still when we went into rebound at 17 BPS.
I noticed that it was a little heavy when it was full of paint, but it won't be full for long!
Conclusion:
This is an extremly fast loader and will not starve your marker. My friend uses it on his 2k2 timmy and ramps it around 19-23 BPS and still no problems or chops.
I could have sworn the rebound was the PSP setting (15BPS). I know the full auto is capped at 10. Minor trivia though, as the hopper can do a consistent 25.
