Well, our locking, parcel sized mailbox arrived from Amazon yesterday and I am about to cut up the plastic mailbox housing at the curb to see if it will hold the weight (about 25#).
You can really go down a rabbit hole trying to determine which box serves individual needs. I watched you tube vids on installing, how strong they are, and how easy it is for a determined man with a baseball bat and a screwdriver can get into any of them.
In the end, my conclusion was that any of them will stop the criminals who just walk down the street, opening mail boxes, and cherry picking any interesting mail. Since nothing short of welded steel boxes will stop a determined crook, any locking box will fit our needs.
In the meantime, while I was contemplating, my resident daughter who lost the checks ordered the box she thought was the best size, a large square one that small parcels would fit it from Architectual Mailboxes.
Gotta get to work on it.
