I've been using a Hornady beam scale since around 1980. Last year I decided to get a check weight set just to see. It was still reading right on. So I see no need for a battery powered device when the balance scale works so well down through the years. Plus I'd always be 're-checking' the electronic scale to make sure it was reading properly.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
