I have both the Lee and RCBS benchtop primers. The RCBS is my go to. Use the Frankford Arsenal Vibra prime to fill primer tubes. No way I’m stabbing at primers to fill those tubes for the RCBS or reloading presses. The Lee works but you have to be careful with the force you use and really pay attention to how it feels when working the handle. I’ve broken it a couple times but that was really on me. Went ahead and pushed when I should’ve stopped and looked. With the RCBS you pay a little more for robust manufacturing. Robust RCBS and Vibra Prime or Lee and be careful. They both work.
