It’s the only electronic measure I’ve ever owned, but out of 10 I’d say I’m a happy 8.
2 things I’ve found to be paramount, as others mentioned, calibrate it every time but also turn it on and let it warm up for a good 15+ minutes. I usually turn mine on and leave it on while I size and prime all my brass before throwing powder.
The vast majority of the time it throws .1 grain under what I want, but it’s easy enough to account for that.
Only other complaint I have is it makes a bit of a mess when using spherical powders like Ramshot TAC. A taller cup would be preferable.
All in all, I’ve been happy with mine.
