I have two of them, they've worked great on my Angels and 'Cocker, fed fast enough (I only skipped when I hit about 15bps on the angel) I mean, they can't feed as fast as a HALO or anything, but they're a great hopper (the activator for the paddles is FAR superior to the revolution, it's a true ANTI jam system, whereas the rev waits for a jam, then breaks it up) I'd recommend it over the rev.
