Rated 4.0 out of 5 by 27 reviewers.
Rated 5.0 out of 5.0 by best secure mailbox for the cost This is a great all metal mailbox. The locking slot is big enough for small parcels, but limits a person's arms from going through to "fish" for mail. Quality is great. However the steel is not galvanized for rust protection. The exterior is powder coated, and looks great. The interior is bare metal. I easily fixed that by spraying Rustoelum's Painter's Touch paint inside to provide a barrier against rust. The lock was a bit finicky and reluctant to open, but after jiggering it for a few minutes, it opens easily now. Overall a great mailbox, best value for the money. Highly recommended!!!

Rated 3.0 out of 5.0 by Mail carrier will not deliver to this box in locked state After installation, my mail carrier said it is not to US Rural P.O. regulations. The curve at the top makes the mail slot too narrow at the top of slot even though the bottom of slot is 10" wide. I can only get mail delivery if left unlocked. April 8, 2015
Rated 4.0 out of 5.0 by Great price for secure mail I installed this mailbox on an existing wooden post. After making a level platform, box installed no problem by screwing through the many holes in the floor of the mailbox (no hardware is incl). The only issue was the very front two holes (out of 4) are nearly impossible to access (screw in screws) because the locking door is in the way. The key works smoothly, door seems secure, slot large enough for most mail (though probably not a box of checks) and roomy for lots of mail build up. I had to gorilla glue the outgoing mail clip to the inside of the door because I could tell the backing tape won't hold up. Mailbox is handsome and decently made. Street dust shows up easily on matte finish, but such is the life of a mailbox. Would buy again. February 25, 2014
Rated 4.0 out of 5.0 by Huge Mail box Great price. So far so good. It's a lot bigger than I thought, I should of checked dimensions but none the less. Great buy. April 7, 2015
Rated 5.0 out of 5.0 by extremely affordable locking mailbox I did an online search through Google, looking for a sturdy yet affordable locking mailbox. My husband and I were somewhat hesitant to even put up a box, as our options of locations for the box ranged from 2 blocks away from our home, to 4 blocks away. I shopped SEVERAL websites and had almost settled on a locking mailbox that was between $70 and $80. Something told me to leave my computer, take a break and come back to do a little further searching. I'm glad I did! I found the same size locking sturdy steel box at nearly half the cost. It's everything it claims to be and more!! The only slight drawback, and who knows where the fault for this lies, was the top of the box was noticeably dented when I received it. I was in desperate need of having the box installed, so did nothing about reporting this back to Home Depot. I still would highly recommend this locking mailbox!! April 30, 2011
Rated 5.0 out of 5.0 by best thing I just bought the mailbox because our mail was being stolen. It was bigger then I was expecting looks good easy to install wood and screws and a screw gun very easy lock works great. I did spray paint the inside and put a piece of cardboard inside. I don't think even a little kid could get there hand inside of it will be able to get most mail opening is big if it didn't fit inside a standard mailbox it wont fit inside this one but u could go weeks without checking mail February 23, 2014
Rated 5.0 out of 5.0 by Great value and high quality! Made in the USA I wanted a locking mail box for the checks I receive in the mail for my small business. I looked around at more expensive mail boxes and found this one. I have been very impressed so far. The mail box installed quickly. It is sturdy and well-built. It is also significantly larger (50%?) than a standard mailbox, so it will hold larger letters. It has a well-designed opening to provide for the larger envelopes. I am glad I used this one!

Rated 1.0 out of 5.0 by Was broke into easily We felt pretty confident after putting up this mailbox. But it was broke into with very little effort. It looks like they just reached in and pulled hard on the interior locked door. A tool may have been involved, the police weren't able to determine that for certain. Please consider a more expensive/better quality box. We have no idea what the scum got, we can only pray it was junk mail. Lesson learned. July 7, 2013
