The Dye one sags very quickly and is generally considered the worst speedfeed you can get. It works, just not very well.
Exalt speedfeed, KM Spines (again, recommended, you've been offered one in a previous post), hurricane speedfeeds, etc all fit Rotors and are designed for Rotors.
And it fits to the Rotor in the same way as any other speedfeed. Take screws out for the colour kit, take colour kit off, remove flip lid, sit speedfeed on the top of the rotor, put on colour kit, screw down. Jobs a good'un.
Rusty: Already loads of videos out there.
