Tired of carpenter bees and snow plows! This works

Would Recommend

Excellent mailbox! We were tired of bees burrowing in the wood and mailboxes being knocked over by the snow plow! So lucky to find this. Easy set up! Very happy with the purchase. Added bonus packages and Mail Drop thru a whole and stack up. You can open it up from the back! Win with all the packages we get!

Good looking, cost effective option.

Would Recommend

Product was easy to assemble and looks like steel from a distance. However, up close it is obvious that it is plastic. The joints could be tighter and if the plastic was slightly more rigid it would allow for tighter seams and a more stable product overall. I had to adjust the top a couple of times to get the mail door to close flush and remain closed against the magnetic catch, but other than that, the installation was straight forward.

XL Mailbox

Would Recommend

Love my new mailbox. Looks great and has large storage for mail and/or packages for when you're away from home. No need to stop delivery! Just remove the floor of the mailbox (just lift it out), and all mail/ packages will drop into the locked area that you can access with key to retrieve it all when you return home.

Seems sturdy but time will tell. We just installed this mailbox and time will tell how well it holds up to the weather.
