The early dye ones seems to be pretty bad i.e. breaking etc. But the newer batches are reported to be fine.
I am trying to fit a halo exalt feedgate onto a rotor at the moment. If they works out well then more than likely the proper exalt rotor ones ill be perform the same.
Theres is a bit of it sticking up as you have to use the collor unlike the halo version, but it ain't bad, Virtue will be brining out rain caps for the rotor crown in the future too
Pros= works as it's supposed to and the future rain lid upgrade is a spot on idea and still have a choice of soft or hard (ooh err missus)
Cons= Should have come with a bigger/stronger spring as the stock rotor lid spring isn't really big or strong enough with the feeder been heavier because of the dense plastic collor
