We get pretty reasonable service. I did get my neighbors mail about a week ago, but that's not very common. However, I did have some medication delivered to my neighbor on the other side, who's house is an AirB&B, and it sat in their box for about 3 weeks before I started searching for it and found it there. That was inconvenient.
Our delivery guy drives a truck and puts the mail in mail boxes on the street. The last two neighborhoods that went up near ours, have an outdoor station with post office boxes like you'd see at in an apartment complex, where the residents go to get their mail. I found that pretty interesting, but I suppose it's more efficient for the USPS driver.
After Hurricane Sally in 2020, we got mail within a couple of days of the hurricane, but as we moved our debris to the front yards for pick-up, and pick-up didn't come, the post office stopped delivering due to the debris. They cut us off for a two to three weeks.
