Question about Google Nest Protect

Thank you. Is the manufacturing date printed on the outside of the box?
Do you do free returns for a full refund if the manufacturing date is not satisfactory?
As the devices are programmed to stop working 10 years after manufacture, I would at most accept a late 2023 manufacturing date.

We receive this item from various suppliers. Unfortunately, it is not possible for us to check the data as the devices are supplied with different manufacturing dates. In addition, we have no influence on the dispatch.
