Same here on the Specialita grinder clogging. After two weeks of use, it clogs after 3 seconds of grinding. Disassemble, clean with compressed air and a wire pipe cleaner on the chute, reassemble. Adjust to coarse running the machine empty, add beans, clog again. Three times I cleaned it but no constructive result. Seems useless.
On the lid, I cut some modeling wood into a square that fits the inner dimension of the hopper, then cut a piece 1cm larger, centered them into layers, drilled a center hole and added a knob. It reduced the noise and isn’t going to crack if someone drops it.
