30+ years ago when I was to corner the market I bought a Dillon electronic scale. It failed within a few months and Dillon replaced it free of charge. About a year later the New Dillon failed. Both drifted about a half grain and wouldn't hold a zero. On the second one I again called Dillon and was told the Lifetime Warranty didn't apply to electronics and they couldn't/wouldn't repair. The solution? Buy another.
Electronic scales are affected by heat and cold, fluorescent lights, anything that has an electric aura and just because. **** that shit. 1010 all the way.
Mine has never failed and considering it is 40 years old, may never. No calls to smarmy, ahole techs. No warming up. No replacing batteries. It too can be calibrated in seconds. Not that it's EVER changed. It's a Ron Popeil scale. Set it and forget it.
