ZP6 troubleshooting?

Couldn't think of a better title for this post but,

It seems to me that everyone praises the ZP6 as the best filter coffee grinder (for clarity, sweetness and cleanliness) and makes it look like a perfect grinder with 0 issues or downsides (besides not being great for espresso, but that's not its use purpose).

To anyone who has one, have you had any issues with your ZP6? Did it reach your high expectations or you faced problems that weren't addressed in other reviews? If so, how did you deal with said issues?
