I have had 2 instances where my Hornady powder dispenser went on the fritz and wouldn't dispense, but would only operate as a scale. I have had ONE instance where it would throw over charges every charge, but it would give an overcharge error reading. Unplug and start over, all 3 times it has gone back to normal operation and was fine within minutes. Out of habit, I check every load on a Lee Safety Powder Balance or an RCBS 505 (Ohaus), out of around 5,000-8,000 charges thrown, if the Hornady says it's on, then it's on.
I picked mine up on a sale about 2yrs ago now, got it out the door for $225+tax.
As a chemical engineer, I work with analytical instruments including balances and scales on a regular basis. The Hornady housing kinda looks cheap, but the user interface for the scale and dispenser is simple, cleaning is simple, and it does what it's designed to do. If I ever wanted to add another, or needed to replace mine, I'd be hard pressed to justify buying another model instead of the Hornady again.
