Customer Reviews

Rated 4.6 out of 5 by 12 reviewers.
Rated 5.0 out of 5.0 by Safe, Secure, Sturdy. Bigger than my first apartment. After having mail stolen for the last time I searched for a locking mailbox and after reading reviews came up with this one. I opted for the larger of the Oasis line and am very happy with my purchase. It will accept packages as large as my old box did. I also purchased the matching 5525 series post and used a #80 sack of concrete to set it. It is extremely sturdy. I changed up the mounting hardware that came with the post to stainless button head screws and stainless nylon locking nuts using the provided washers. The post was plumb but after mounting the box it was slightly sloped forward so I used 2 stainless washers to level it. The box is powder coated and the hardware is stainless steel which will be nice here in the Pacific Northwest so the hinges won't rust out. I don't hold my mail anymore unless I'm gone for over a week or expecting large parcels. I don't experience the problem with catalogs or magazines like others have reported, at least not yet. Water does bead up on the top of the box because it is flat. I don't want to slope the box so I'm going to try some car wax or maybe rainx to help that. The rubber door seals are good and tight. All in all, a tad spendy for a mail box but we all know you get what you pay for. The box and post are well made and look like they will give many years of reliable service. The shipping was fast and "free". Ordered on Monday afternoon and delivered that Friday. With more and more online shopping, small parcels are being delivered to our homes more frequently. Get a mail box that is safe, secure and sturdy. One that is large enough to suit your future needs. April 10, 2016
Rated 5.0 out of 5.0 by Quality Secure Mail Box This mail box is well made and well priced compared to like items by other manufacturers. We purchased the square matching post. The colors are the same but have different names (beige and sand). February 23, 2016
Rated 4.0 out of 5.0 by Could be better designed This is supposed to be a security type mail box, however it has an issue. The postal carrier pulls down the handle and puts the mail in. When the door is closed, the mail slides down into the secured box below. The problem is, magazines usually don't get into the secured area, thus, if any important mail was put in on top of the magazines, it may not get into the box. The back of the slide is too long which prevents the magazines from falling down. I am considering cutting the back of the slide to make more room for the magazines. Also, the instructions say to mount it level, however I have found that when it rains, some rain stays on the top and when the mail is delivered, some water can fall onto the mail. Not a lot, but some. I put a couple washers under the front bolts to raise the front just a little so the water will run to the back. Overall construction is good. November 10, 2015
Rated 5.0 out of 5.0 by Great mailbox Solid design , not your standard locking mailbox. Easy to install. September 1, 2015
Rated 5.0 out of 5.0 by Nice Mailbox I purchased in March of 2007, had it installed in a brick column at our newly constructed residence in May of 2007. The mailbox works great. Nice rubber seal around top and bottom doors to keep everything dry. Top mail drop door is pretty much theft proof and large enough for common over-sized packages (checks, software etc.). Well constructed,and feels solid. We did not have the red metal flag installed as this gives thieves for outgoing mail, well a red flag!! Instead we use a small foam rubber one that when the outgoing door is opened the mail carrier can see. Nice spring clip for holding outgoing mail on inside of mail drop door. Painted finish is nice and durable as well. Can hold at least a weeks worth of mail. January 23, 2008
Rated 5.0 out of 5.0 by Architectural Oasis Locking Mailbox -excellent product I highly recommend this mailbox. It is very strong and large enough to accept fairly large packages from the postal service, lots of magazines, or allows me to let my mail accumulate for a few days while I am away without worry. It is of very high quality. This was a replacement mailbox, as my original one (exact same mailbox) was destroyed in an accident. I had the my original one for over 4 years and it continued to look good and work perfectly. I expect the same from this new one. It is a little expensive but it is worth it. November 13, 2012
Rated 5.0 out of 5.0 by I love my new mail box. Several of us have had to go to locking mail boxes because of mail getting stolen. No one has a mail box like mine. The larger size is fantastic and I especially like the ivory color. I did not want to go to a locking mail box because I had a very large regular mail box for packages, etc. When I found the larger locking mail box I ordered it right away. When it got here I liked it even more. May 3, 2011
Rated 4.0 out of 5.0 by Good, but needs modification. The inside base is rough with the bolts and seams exposed. I needed to build a base that was smooth and fit in the bottom. February 25, 2014
