I have a Halo Too, it's pretty damn good tbh, put over 4K balls through it last time I used it and it was immaculate inside, didn't break anything, never jammed, the only down side too it is the lid is quite flimsy, but an Exalt Speed feed for £9.99 will sort that out anyway. Doubt a Rotor is truly worth twice the price over the Halo imo, does the job perfectly for my Mini which is set to max fire rate at all times, keeps up and never missed a beat.
