The rational basis for how to choose tools for your powder handling chores is how many rounds you weigh out at a time. If it's a few dozen the digital dumpsters are foolish, IMHO. If you do a few hundred at a time, yeah, they are helpful. The gray area in between is a toss up.
Personally, I never feel a need to hurry my precision loading and prefer to KNOW I'm in control every step of the way. I will not relinquish that control to any 'made in China' electronic gimmick.
I would hardly call an electronic powder dispenser a gimmick. As far as volume loading, it does not matter to me if I am putting together 30 rounds or 300, I like my dispenser. I too never hurry my reloading, despite using my "electronic gimmick". BTW, do you consider a calculator a gimmick? A couple of sharp pencils and an eraser works too!
To each their own, but calling them foolish for loading a few dozen rounds is your opinion, and not necessarily shared by others.
