I've used the Lee Safety Scale (very finnicky but also very accurate if you know how to use it) RCBS 5-0-5 (excellent balance beam, much faster and less finnicky than Lee) and Hornady G2 1500 digital which is a steaming turd . It doesn't hold zero, wanders all over the place, occasionally agrees with the 5-0-5 momentarily then swings way out of whack. Passes its own cal every time but constantly changes its readout. I returned it and got another that performs exactly the same. I've tried letting it warm up for entire reloading sessions, tried new batteries, tried turning the lights off, tried other buildings. It is 100% useless in every sense of the word. Is it zero? Or - .9 gr? Or wait + .6 gr? No + .3 gr. No wait - 1.3 gr.... and on and on. Put a weighed charge from the 5-0-5 on it, lets say 23.5 gr. Hornady says 24.6. No 24.7 wait, its 24.0. Ok, lied its 23.5. Just kidding its 22.9. Haha my bad 25.6. I don't know, throw me in the garbage I'm high AF.
