I have the T-7 with an extra die head and have been using it for about 2 years. It has been very consistent and my runout on loads has stayed under .001", (all brass is neck turned for tight necked chambers).
I set up bushing neck sizers, seating dies and mandrels on the T-7, but I FL size on a Big Boss.
I wish it had a positive stop on the rotation, so I could loosen tight dies a little easier. Another thing is the tight space around the die rings, it's often hard to loosen rings for minor adjustments. My initial head had one hole that was not true and case necks always hit the edge of the die. Redding replaced it.
It's a very handy tool for most reloading dies and does save space. If you check that all 7 holes are true, you should be very pleased with it.
