I got the pulse for Christmas, and all i can say is WOW. This hopper rocks, the different modes are a plus. I don't have the RF chip installed on my shocker because i don't think the older boards you can solder the chip onto it, or it doesn't have a place for it. Also people say that its 1 chip per gun, you can un-solder the chip as easliy as you put it on. Cause i have installed 3 of them for my friend's gun's.
The only thing that i have a problem with is that the hopper will turn off ever 2 minutes or so if not in use. It has turned off a couple times through-out the game which really pissed me off, But whatever...i think it was because the batteries were running out. The 2nd thing i had problems with were the battery door and screw. The screw is so damn small it wasen't even funny. Then the door was awkward. I thought the first time i took it off i broke something.
All-in-all i don't hate over little things, i just learn to adapt to them. As with all my reviews nothing gets a 10 out of 10. Due for the reason that nothing is perfect.
Buy it if you got the money...One of the best hoppers i have seen in a while.
