Great deal for the money. I added a spring to the door because my mail carrier didn’t always close it. Now he has to hold it open to insert the mail and door is always closed lol.

Very well made. The design lets fairly large things go through the door and drop down into your mailbox. Others I've seen are more limited to letters only or very small packages. I bought a larger version which is approximately 14W x 16D x 20H, and I love it. Packages in envelopes such as smaller medication bottles and DVD's slide into the mailbox. Big bottles, larger packages, etc will not fit of course. Seems to be pretty secure. Devoted thieves should be able to break into it pretty easily, with some tools, but I haven't seen any that look more secure than this box. The lock could be better, I may see if I can get one with a higher security (round) key at the hardware store. Thieves also break into the USPS "cluster boxes", and they are about as good as they get. This seems to serve my purpose as well as any I've seen, and my neighbors all have locking mailboxes of differing designs. I got it with the post, and all fit together well and was easy to assemble. I set it in a hole and put a half a sack of redi mix in the hole. I kept the concrete well below the lawn and put the sod back on the hole and the concrete doesn't show. It's securely planted with a strong post which came with all hardware. Nice finish and good looking too. I got sand color to keep the heat down vs. a dark color. Has a sturdy little clip for outgoing mail inside the door and a nice flag that operates well.By the way I used a level and tilted it down slightly to the front so any rain will drain out the front of the door and not migrate back into the mail in the box. It does have an overhang to keep rain out and a gasket, as well as holes in each corner to drain but I wanted to be extra sure my mail stays dry. My old mailbox soaked my mail in the rain, and boy is that irritating!So to recap the security issue, I can't say this mail box will be completely secure by any means but I haven't seen one that is better. Reasonable price for the quality you get in my opinion. (Once thieves went up the street and stole everyone's mail but it was from unlocked boxes. No problem since we all got locking boxes, but we have not had real break in attempts, just grab and run thefts. Other thefts in neighborhood including home break ins have been unlocked cars or homes or mailboxes. These mailboxes work fine to prevent these thefts.)

This is a very large, very well-made mailbox. I recommend it.The top security drawer now has an extension on it which may address concerns that somebody could reach in. Since the box is 20 inches high, reaching in is close to impossible either way. The trade-off is the drawer increases security but also means no boxes can fit in. Cutting the security drawer shorter to make it easier to put boxes in would be very, very difficult (only way I can even think of would be to use a pneumatic cut-off tool).White is good to minimize baking the mail, especially for folks who get their prescriptions by mail.I had a steel post welded up and Line-Xed it. The 4 box mounting holes are on approx. 4" by 10" centers so a regular post would be too narrow; there are wide synthetic posts at Lowes & Home Depot or you could use 2 wood 4x4 mailbox posts. Then I used stainless bolts with stainless fender (big diameter) washers.This is not a safe. The mailbox (just like your house) could be broken into (or pulled out of the ground) (I used 3 80 pound bags of concrete).It is not "mailbox baseball" proof, but probably 'resistant.' If 'mailbox baseball' is a problem in your area, then have a welding shop make you a mailbox.

This is a high-quality product. It is well-made and is finished well. The entry door is designed and operates much like a standard, US post office, mailbox. When open, the rear portion of the door blocks access to the lower chamber of the box. Mail drops from behind the entry door into the lower chamber, when the door is closed. The door to the lower chamber is secured from the outside front by a keyed lock. The mailbox itself is all painted, heavy-gage, steel construction. It should not be easily damaged by inclement weather conditions or light impacts. It is doubtful a single swing of a bat or club would severely damage it. I also doubt if an exploding plastic soda bottle would do serious damage to the box.The security level is low, but sufficient to prevent the casual passerby from reaching in and extracting items. However, I feel quite sure the lock could be easily picked and the lower chamber door could be pried open by a determined thief.The box has a flag and the entry door has an inside-mounted clip to hold outgoing mail, for those individuals whom utilize mail pick-up from their home mailbox. However, there is no security with this feature.Those who want to mount the mailbox on a post should consider purchasing the optional 46-1/2 in. long, tubular steel, mounting post. They may also want to embed the post in concrete. It will require about one (1) cubic foot of concrete (apprx. 150 lb). The mounting plate on the post fit right up w/ the four (4) mounting holes in the underside of the mailbox. Threaded-fasteners are supplied w/ the post. It makes a great looking and highly-functional, finished package.One additional thought, those homes on motor routes that have newspaper delivery will have to retain their present newspaper receptacles as this box has no provision to receive and hold a newspaper. Although, a newspaper receptacle could be mounted to the side of the mailbox, the highest point on the mailbox mounting post is too low for directly mounting the paper receptacle.Update as of 10/18/2012:The mailbox continues to function well w/o a failure of any component. Painted surfaces continue to hold-up well, too. However, there are a couple of minor issues w/ the box. First, larger items may not always drop into the lower chamber although they fit into mouth of the box. When the door is closed they do not clear the back edge of the flap and drop. Thus, they could be pulled back out of the door defeating the security feature. I'd categorize this as a design flaw. Second, birds like to perch on the flat top surface of the box and it tends to accumulate bird droppings. This can be unsightly and messy.
