On my lee pro 1000 it works great even being a size or 2 to large. If you have the bullet feeder installed, which I do, it can be a bit of a pain tightening the powder die due to how close the bullet feeder is on the next die...all in all it's still the best tool I have used for tightening lee dies on "my" setup.
Pros: Fits the Lee dies well enough to tighten them
Cons: Can be a little tough between some dies, but I'm using it for a different press than it was intended.
