I am certainly not impressed with PACT scales. I had mine for less than a year when I discovered it would not zero with the powder pan sitting on it. I called PACT and was advised that it was under warranty and for $14.95 to cover shipping and handling, they would repair or replace it. So, on January 6 of 2013 I sent it back to them in Grand Prairie TX. As of today, they still have not gotten it fixed and tell me it may be several more months before they do. They say it's a problem with the chips in the board with the model I have. I sure as the devil don't want to buy another model to replace the one I already have. I thought I would spread the word in case you are thinking of buying one.
