    • nice and sturdy
Color: Black Pattern Name: Mailbox + Adhesive
this mailbox is secure, easy to install and well built. It is very good for regular mail and magazines but for those who receive packages it will only accept very small packages maybe 2" or so thick due to the slot that the incoming mail has to slip through. It costs a little more than some of the other models you will see but it is thicker and worth the extra price for the extra strength especially if you have kids who like to drive by and give them a whack with a bat ... show more

    • MAIL BOSS is the BOSS!!!!!
Color: Granite Pattern Name: Mailbox
I purchased the Mail Boss 7105 curbside, security, locking, mail box and the MAIL BOSS 7120, in ground, powder coated, Steel Mail Box post, to mount the MAILBOSS on. I mounted this combination into about a 12" post hole dug and filled with most of one bag of Quick setting concrete mixed in the hole . I also set the post into a half cement block, above ground and filled the space around the post with cement and set some large landscape rocks into the surplus cement around the post. I set a two by four on top of the post (to protect the post) and hammered the post into the ground about 4" to keep it upright and steady while my cement dried. I sprinkled the remaining cement into the rock cracks and then sprinkled water to wash the cement into the rock cracks. This mail box is solid !!! This has the MAILBOSS very secure with over 100# of weight holding the MAILBOSS and post in place. The MAILBOSS and steel post have a matching powder coat finish and looks great. The MAILBOSS is a well built ,great looking, and very secure mail box. The instructions are very simple and easy to follow. The MAILBOSS comes with a universal mounting plate with screws for the MAILBOSS post or for mounting to your wood post. I followed a previous reviewer suggestion to mount the MAILBOSS with a slight forward tilt to make rain run off to the front of the box. My mail has been completely dry through several heavy thunder storms. This mail box handles a large amount of mail and small mail packages that can only be accessed with a very nice and sturdy security lock. There is a nice dry place to put out going mail but this mail can not be secured with a lock. Most mail delivery people will not carry your key to open a locked mail box. Think about it, how many keys would they have to carry and sort through too pen each box? I suppose any mail box could be "FISHED" with enough time and effort, but this mail box will give you very secure mail protection. This is a great , very secure and easy to use solution the your mail security concerns. My mail carrier loves this mail box and has no problem using it. Be sure to check box height and distance from the road mounting requirements with your local post office. ... show more

Finally the post office allowed us in the countryside to have our own personal mailboxes. I ordered this one as it is a good size for mail and small packages. It is lockable and so protects your mail well. It is strong and looks like it will last a good long time. For a while some insects wanted to live inside but now they have given up that idea. All in all this was what I consider a really good buy. ... show more

    • Large mailbox for lots of mail, not large packages
Color: Black Pattern Name: Mailbox
Review Image by Linda L. Linda L.
It’s definitely heavy duty and great for businesses or people that get a lot of mail. I thought the big box could hold large packages but no, it only excepts letters that can squeeze through the top slot. But it’s secure and strong as well as good looking. I’m not disappointed.

    • Seems like a good product but…
Color: Black Pattern Name: Mailbox
This is a very strong, heavy mailbox. It’s very easy to install, however, one of the holes where you attach the box to the mounting bracket was very badly misaligned. I couldn’t deal with the idea of repackaging, hauling and returning, only to have to go through the entire process again (63 year old woman doing it alone) so I bought a metal bit for my drill and made the hole bigger. I strongly suggest you check that the holes align BEFORE you install. ... show more

    • AWESOME!
Color: Bronze Pattern Name: Mailbox
I love this mailbox! The price gave me cause to pause (at first), but I have done my homework on mailboxes. I've tested them at stores, and even walking up and down my own neighborhood, to see if they truly were 'secure'. Every one I'd try, I could get my arm nearly all the way to the bottom (and all the way in many cases). THAT'S NOT SECURE, LOCK OR NOT! Think of kids walking home from school (with much smaller arms) for instance. I've had my mail stolen before with my old mailbox. I feel much more secure with this one. NO WAY anyone is going to get inside the slot to my private mail and information! The box is made of beautiful sturdy, well built material (it's heavy!). I doubt I'll ever have to change this box out or buy another one. My mail person can even fit relatively small packages inside (not too large...but Mail Boss does have boxes that can handle larger ones if it's your preference, just do a search). This one is perfect for my needs, most anything my mail person delivers, he can get into the box. If not, he'll leave it on my porch, as usual. The locking mechanism is not flimsy, and easy to open with key (I notice other brands I'd have to jiggle the key and so on to get the very cheaply made lock to open, not to mention it would be easy to just break it open anyway). This lock is SECURE. This is well worth every dime, believe me. I have neighbors now asking me where to get it. OH and no worries about kids batting it down either, I cannot stress enough how strong this mailbox is. I LOVE IT!!! Even comes with extra keys (keep your paperwork and register your box, because IN CASE you lose your keys you CAN get another lock, they thought of everything!) There's also a shelf where you can put small outgoing envelopes for your mail person to pick up. I'd advise against putting anything with personal information though, just because that part is not locked (the mail person would have to have a key if that were the case). But it's quite convenient for simple outgoing mail where you are not concerned about identity theft. Customer service is top notch as well. I had a very minor flaw in a spot of finish on mine and contacted Amazon asking how I could fix it, and they immediately sent me a new one with a PREPAID return label for the other one. It was minor enough I did not expect that, so what a pleasant surprise, THANK YOU AMAZON! The new one is absolutely FLAWLESS. This is the 'Sherman tank' of mailboxes! I HIGHLY recommend, am I clear enough? This is a clear example of getting what you pay for...expensive, but WORTH IT! ... show more
