If it dosent last my lifetime, RCBS will replace it. They have already replaced broken parts that were admittedly MY fault. Apparently, Redding has the same policy, but I haven't tried them. Good dies though. It seems to be the general concensious that you will still want a good balance scale, even if you have a state of the art digital. I haven't tried these either, but I have friends that swear by them. I would not mind having one...but electronics fail..eventually it will die.
As far as balance scales go..some of them have a little peice of metal that you move accross a series of notches for tenths. This type can be easily bumped while you are loading and knocked easily off your # setting. I have one, and do not like it. I also have the 10-10..the 1/10th setting will not move by accident and I trust it a lot more. .5 over MAX load in some pistol loads can blow it up in your face.
