I was impressed with the ease of installation. Unfortunately, I did not receive the decorative cap I requested. After contacting customer service, I was pleasantly surprised and impressed with their response. I received a replacement cap in a couple of days.

This is a great product and a very easy install. I am so happy with decision to buy this mailbox. My old mailbox was hit and the 4"x4" post was broken off about half way up. Instead of having to dig out the old post, I simply put the plastic post over the old one.I did dig the dirt out down to the bottom of the cement base. I am so impressed with the final product. I saved money by installing it myself, my husband was super impressed that I put up the mailbox and I can't believe how easy it was to install. I did have one question regarding the screws and I called the customer service department and the representative was very helpful. The final product is a beautiful high quality mailbox.
