Rated 4.4 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Quality Mail Box High quality, good looking mail box that was easy to install. June 27, 2016
Rated 4.0 out of 5.0 by Great Mailbox This mailbox is perfect for what we needed and didn't cost an arm and a leg. Holds large items without having to stuff box. May 17, 2016
Rated 1.0 out of 5.0 by Not as secure as the sales pitch would have you believe Thieves can open this mailbox without a key about as fast as you do with a key. The tang on the locks bend easily. Saw a guy drive up, insert some kind of tool and pop open my mailbox (this design) and drive off - all in about 20 seconds. The rear access door may even be designed so that the rear lock's tang can be bent allowing acces should the locks fail. It looks good and has withstood lots of weather, but it'll only keep young vandals out. April 2, 2015
Rated 4.0 out of 5.0 by New security Mail box The mail box is very strong and sturdy, was easy to install, perfect size for small pakages.and large envelopes. April 28, 2015
Rated 5.0 out of 5.0 by Stands out on the street Well designed, stylish mailbox. Stands out on a street of conventional mailboxes. Took about a half hour to install, not counting digging up the old post. Make sure you use with the matching post ($100). I used non-mix Ready-Crete (pour in hole and add water). Only area of improvement would be the lock and key, which could be of higher quality. February 21, 2015
Rated 5.0 out of 5.0 by Good experience The mailbox was just what I expected. 4 keys were provided and are keyed for the same lock, it is good to have the spare keys. Note the mail slot is smaller than expected, so the mailperson will have to come to the door with even small packages. April 12, 2016
Rated 5.0 out of 5.0 by Nice Bought the deluxe post with it. Very easy to install. Cemented the deluxe post of course. Very easy to attach. Good looking mailbox. March 14, 2015
Rated 5.0 out of 5.0 by POST-MOUNT ROADSIDE MAILBOX Very Easy to install, took less than 30 minutes to put everything together. Been up 3 weeks.; had high wind (30 mph) that brought down a tree that demolished a neighbor's car and the mailbox is still standing. Guess time will tell...but so far, so good ! January 7, 2015
