Grind By Weight is a plus with a standard hopper but for a Single Dose Grider, not so much. At least that’s my take on it but the caveat is that I haven’t used it.
But that caveat aside, as others have said, the Orbit looks like a top quality grinder for a competitive price without the GbW option. So use the latter feature if you feel it’s better, or don’t. Either way it’s a serious contender in the mid tier flat burr market.
