Sturdy mailbox and weather resistant.

We bought this mailbox for our new home and it has a neat, sleek look while being large enough for larger pieces of mail

durable and secure

Would Recommend

[This review was collected as part of a promotion.] I have been using this mailbox for a few weeks now, and its such a relief to not have to worry about it being stolen or tampered with. Its easy to use, and looks really nice too. It only took a couple minutes to install and I have really enjoyed having it. I would recommend picking one up. I have had several compliments from neighbors and friends since I replaced my old one! Check it out!

Very Tough and Sturdy Product

Would Recommend

[This review was collected as part of a promotion.] Architectural Mailboxes - Sienna is sturdy ,tough ,black metalic is a very up to date and classy look for my mailbox. It was somewhat easy to put up, drill the four holes needed for the one and a half inch screw taps needed for the job and it went together very smoothly and it even comes with keys to lock the box anytime needed.I received this product free of charge in return of my honest opinion about the product.

Solidly Built

Would Recommend

[This review was collected as part of a promotion.] Very nice mailbox, it has a nice feel and just the right amount of heft to it. The overall feel is very nice. A very wide mailing slot can fit a the old holy-joe envelopes for those older folks that know what I'm talking about. The lift top also has a nice feel to it. And the door fully opens giving full access to whatever is in the box. The locking mechanism works well, nice and smooth.

Really nice

Would Recommend

[This review was collected as part of a promotion.] This is a really nice mailbox. Never thought I'd say that. It's very solidly constructed and feels like it will hold up very well over time. It's super simple style wise, but somehow looks nicer in person. It's bigger than expected and will hold magazines/large envelopes. I love that it's lockable. I travel a lot for work and will feel more comfortable knowing my mail is secure until I get home.

Love it

Would Recommend

[This review was collected as part of a promotion.] Does the job and looks great. I attached some stainless steel door numbers to it and so far so good. The only addition that would have been nice is a template for the holes to be drilled. I also get why people say the lid is noisy when it shuts but a rubber pad on the lip soon sorts this out. Great value for the money as many others in this style are way overpriced or have poor aesthetics

Built strong

Would Recommend

[This review was collected as part of a promotion.] This mailbox is perfect. It is built very strong. The top opening is wide enough for bigger packages and having the lock sets my mind at ease knowing nobody can get in there. Installing it only took a couple min
