I have used a viewloader max which is a decent hopper and i have used a regular hopper which sucks
I use the electra and i have a smart part barrel and a evolution 2 hopper and i just use CO2
Doesnt chop paint, fast and battery last awhile
This is a Great hopper, I have a spyder electra and shoots really fast because of the rocking trigger and this hopper keeps up with it. I bought this hopper of my friend for 25 dollars which was a real good deal but the lid was broken so i just had to buy a new lid.
This is a great hopper for its price.
It is a really good hopper and it works really well on any gun. It is much better then any hopper i have used.
