Fwiw, I have used quite a few digital scales. I have had very little to no amount of drifting. Calibrations are remarkably consistent. However, I have used so many because the strain gauges in them seem to fail eventually. I am currently using an OHaus Scout with relatively low precision but the best durability yet.

I also use a beam balance and compare across scales. A $35 used OHaus beam balance is really hard to beat.
