This is for you rec ballers or pb'ers on a budget.
The Empire Reloader II is a sound activated hopper so each time you fire and it goes 'bang' the device will push a few balls into the feedneck. So it's alot better than a gravity hopper in that your certain to have a ball in the breech each time you fire. I believe the BPS is somewhere in the lines of 12-14 bps. It's also decently quiet since it's only whirring around while the gun is firing.
I haven't had this thing blend any paint and my ball chops appear to have gone away (I only had one chop from using 4750 rounds).
The magnetic lid is pretty good. I would prefer slightly stronger magnets to assure you don't spill any balls during a dive. Hasn't happened to me yet but the potential is there.
The shell of the hopper is about the same to most other e-hoppers out there so it's on par with the standard but I just wish they simply use a more flexible plastic rather than something that could shatter.
Battery life has been real good in comparison to the devices I have used that constantly are agitating the balls or pushing the balls down. It simply turns on each time it senses a loud enough sound, ie. paintball gun firing, and when you not using it, it goes into a standby mode. After enough time it will shut itself off. I believe this number is 30min but I've never been out that long to find out. But the on/off switch is an easy push button and I don't expect that to be much of a problem for most. I also like the fact that it uses a battery door that snaps into place and installing the batteries is simply sliding the two 9v batteries into the compartment rather than using battery tabs that dangles from two wires.
Feedneck is on the big side and could be an issue for some. This will require you to sand the feedneck down or get a device that will accommodate the size.
Retail I think this thing is about $50 which isn't bad based on the performance of the hopper. Now if you can out shoot 14bps or like to be on full auto I would get something else. This hopper has been very reliable and beats the heck out of just using a gravity hopper.
Note: if your gun is real quiet this hopper is not for you either. But as I said earlier, rec ballers and budget pb'ers (who typically don't have the high end guns thus they're on the nosier side) should find this a great hopper to use.
