I use the spyder fenix acs and the accessories i have for it is a 14inch proto barrel, and an electric hopper.
Can be used as regular hopper, works good, cheap, looks, adjustable speeds
Not that fast, always rotates,
I think this hopper is pretty good for the price because if you want your paint to keep up to your gun better than a regular hopper and you dont have enough money to get one of those sweet ones this is the kind of hopper to get because it is cheap durable and it will keep up better than a regular hopper so you will reduce breaking your balls at least by 50%.
I would get this if you are not loaded with money because overall i did not have any problems with it and it helps even though my gun is electric this hoppper still makes a difference.
