I have had a Pact electronic powder dispenser for over ten years. I have never had a problem with it. I don't load all the time. I load handgun and rifle. I throw a charge with a powder measure then dump the under charge into the powder pan and the dispenser completes the charge. Sometimes the unit will not be used for a year or more. Every time I fired it up it worked. Today I started it up and when I pushed the calibrate button on the dispenser it would not calibrate. My thought was I will upgrade to a later model. Lyman or Hornady. After reading the Lyman & Hornady reviews on Midway I think I will call Pact and send mine back for repair. I will appreciate everyone's experience with Lyman, Hornady and Pact. Have people had many problems like the reviews say about Hornady or Lyman? I question the reviews. I will call Pact today--- Thursday 9-25-14 --- and see how there customer service is. Thanks Norman
