Efficient Solution

from Caldwell, ID – Verified Buyer

Someone hit & ran my old mailbox so I needed a quick & easy way to get a replacement that wouldn't break the bank. This one arrived quickly, is sturdy, was easy to assemble (even for untalented me). I did hire a handyman to finish it up for me (1/2 hour) but that's just because of my old damaged mailbox complications. I only gave it a 4 star because I think the uncovered bolts in front are ugly. Otherwise a good choice.

Fine for the price

from West Richland, WA – Verified Buyer

Plastic wasn't my 1st choice for a mailbox but the price was right and it seems to be quite durable and was very easy to install. The box area is roomy enough to accommodate large deliveries of mail including small packages and the newspaper slot is nice. It just lacks that traditional look of a metal box on a post that I'm accustomed to.

Easy to install!

from Oak Ridge, NJ – Verified Buyer

I was pleased with how quick the item was delivered and also pleased with how easy it was to install. I just cut the old mailbox post to the height listed in the instructions and proceeded with the install. I only wish that I knew how inexpensive this product was much sooner. I've wasted so much money on other mailboxes that get rusty, smashed, or generally fall apart.

Exactly what I expected

from Spring Grove, PA – Verified Buyer

It is certainly not an original mailbox because everyone has one. They are very well made and easy to install. The price of it was awesome and was delivered in less than a week. Impressive.

Nice Mailbox

from Georgia – Verified Buyer

I think the mailbox is just fine. I don't find it attractive, but I didn't want to spend a lot on a mailbox, so I chose this one. I hope it lasts a long time. It seems to be very sturdy.
