I have the auto charge unit. I have used it for years and I can't imagine reloading without it now. My digital display isn't as crisp as it used to be but it seems to work very well. I can't complain about anything. Inserting a McDonald's straw into the tube helped get more consistent charges because without it sometimes it would drop too much when it was trying to trickle out the last bit of the charge. Overall, I'm happy with it. I'm talking about the auto charger that drops powder onto thte scale and not just a digital scale.
