I recently got a Lee ergo prime tool as part of a purchase of other used reloading stuff. Tried it out, and was disappointed. Then I figured out that most of the trouble was parts "sticking" in the piston and toggle. Sprayed those moving parts with an aerosol teflon lubricant ( Remington dri lube) and it works quite well now. I wouldn't buy one, but that might be worth a try if you have one and it doesn't work smoothly.
