I agree with everyone here about just how good this thing works. I honestly haven't had one issue yet. Is it expensive? yes! but IMO it is worth every penny. My RF100 will still get to do CCI 500's during long runs, but if I'm doing 400-500 reloading sessions the PAL Filler is super reliable and headache free. I've got the VP too, and the only major issues have been with Winchester primers. Though every now and then you do have stop it for a jam. The PAL Filler just works so consistently there is no comparison. Especially with the Winchester primers, it's a tad slower with them but no flipped ones at all.
edit: one thing to note, Mark 7 isn't carrying them right now, they are not on their website. Umberto says you have to go through them now. See FB
