5 Nest smoke alarms. 4 batt, 1 wired with battery option it seems. Removed from a rental as the wired expired March and the 4 batt expire in April. Can sell all or split. Price is for 1 item, but happy for bids on all/some! As far as I know they all still work (unsure about wired as disconnected and no batteries). Can split f required. Happy for any questions.
