grouped into themes · share of opinionated mentionsThe failure mode
~1 in 13 long-term reports mention a failure, but reliability is not fully measurable here — the long-term owner pool is too small to confirm that rate. Isolated reports name the chute and clogging-related components most often, with onset typically within the first 4 months. Warranty outcomes lean unresolved, so don't count on a straightforward fix if something goes wrong early.
