Had one when they first came out for a while but it had problems, the chucks that hold the tip of the bullet were undersized for the machined hole in the stand/cradle they fit in. They wobbled around loosely with a lot of play making it hard to measure run out let alone correct it. I assume the newer units are manufactured to better specs. I agree with Chuck that correcting run out with these type of tools has an effect on neck tension especially with short bullets that are not seated very deep into the neck.
