I have one. Well should say my dad owns one. I rarely use it as I dont load up more then batches of about 50 rounds at a time. By the time that **** lyman warms up in 30 minutes, I'm more then halfway done on my balance beam scale. only time I've used it was when I sat down and loaded around 600 round for my 222 when I went PD shooting. It worked just fine. My dad uses it a lot more then I do w/out any problems. He loves just being able to push a button and the powder comes out. Seems to be pretty accurate and consistent, never had a problem there.
