The newest rendition of their safety prime is way better than the second version. I have had to pull the handle and stop what I'm doing to guide the primer in with both hands ever so gently and click it in place until now. The new one is the cats meow. Definitely increased production time. I can zip right thru the resize, deprime and prime pretty much instantly. A great improvement IMHO. I know some of y'all knock Lee stuff, but it works fine for my needs and productivity.
