Question: How is item installed?
Document: This replaced a mailbox damaged by The storm Sandy and i'm very pleased so far. I did have a contractor friend who installed this for me so I can't speak to installation difficulties but it looks nice and seems to be working just fine so I'm good.
Received product with scratches and scuff marks to various parts of the post. Had to  spray black paint to make presentable. Two of the screw holes had to be enlarged to allow the machine screws to connect. Other minor but irritating items. Overall, poor workmanship for such an expensive item. Finally got it all together and up looking good - no thanks to the manufacturer. Would recommend better quality control, improved packaging and engineering. Do not think I would ever buy again or recommend to another.
excellent service and product quality
We were looking for a mailbox that would blend into our new landscaping and hold up to our weather. This mailbox is extremely well made and an excellent value for the price. It was easy to assemble and mount.
This is an excellent well built product that I beleive will give me years of service. It was shiiped promptly and as advertised
Mailbox arrived well packaged with all required installation instructions and parts.Would have preferred a better location for lettering to be positioned.
I really like the looks of it and the way it is built. I would recommend this to my friends. I was very pleased how everything was handle from the time we tried to fine parts for our old one to when we ordered our new one. It didn't take anytime for shipping also everything was great.Thank you for the great service.
I like the mailbox very much. It looks good and works well. It would be nice if it locked and even better if you could get house numbers for it. Even so, it is perfect for the front of my house and looks good.
