hthec I think people have been struggling with cast burrs, so would be surprised if this does well with them. The gorilla gear are quite a traditional geometry aren’t they? I’m sure they’ll be fine if so.
I’m actually not so keen on the aesthetics. I’m sure it’s probably the best performing grinder in a wind tunnel but I’d prefer to see it more angular, similar to the Weber Key. If they could work on the proportions a bit, even better. It’s interesting, that layout seems more prevalent with conical burrs, whereas vertically mounted flat burrs are becoming more common. I do like the look of the P64 but thinks it’s proportions are also off a bit, quite tall and slender. I’d just love a grinder that’s designed with out of the box alignment for that £500 mark. The kopi has at least produced a very good thing for a good price and proves it’s possible.
