Never seen those before. I would hate that. Of course we have no new neighborhoods in my town.
As the owners of a 12 unit apartment, we just spent $1500 ($1250 mailbox plus $250 installation) to put in a cluster mailbox. The tenants all prefer it, since the individual boxes are locked which discourages theft. It replaced individual rural type mailboxes on a common base.
The cluster boxes look better, take less room and are more secure. What is not to like?
