Thought I might buy one. Looked at the reviews. Lots of good reviews but every model also has some scary reviews as well. Scary as in "dispenses inaccurate powder charges." This has me wondering if my simple digital scale is accurate! I've never owned a beam type scale, I've always been digital. I keep it calibrated. I haven't blown myself up yet. What are your opinions? Digital scales and combination scales/dispensers. Do you trust them?
