I often miss parcel deliveries because no one is available at home during working hours. I am considering installing a secure delivery box, but I would like to understand how effective it is in preventing theft and protecting packages from rain or damage. Which material, size, and locking system are most suitable for regular household deliveries? Are smart delivery boxes with access codes better than standard lockable models? I would also appreciate advice about choosing the right installation location and checking whether different couriers can use the box easily. Please share your experience and any practical points a buyer should consider.
