@golnziwe — yes, warranty extends by the time you were without a working unit. Sorry that wasn’t communicated.
@El_burrito — fair point. Two distinct issues: (1) a solder defect on the charging IC where vias in the pads cause pins to fail weeks/months later — <~3% of units (working on getting the excact nrs), fixed in the latest batches; (2) input voltage — our system needs ≥5.1V, and many chargers (Apple, computer USB) fall back to 5V. A 9V+ USB-C PD charger fixes it; our recommended 20V charger isn’t affected. Both corrected on new stock. Replacements come from a mixed pool for now, but the share of fixed units rises as new production lands, and warranty (with extension) covers any that fail again.
Edit:
- Warranty restarts from the replacement unit (need to verify)
