Great product, well made, perfect.
Justin was amazing to work with! He went through 4 or 5 revisions making sure the mailbox cover fit perfectly. I rarely leave feedback, but this whole experience was phenomenal! 10 out of 10 for sure!
Very well made. Perfect fit.
The door fit where I needed it to fit.
My mailman broke my metal mailbox door that is housed in a brick tower. This manufacturer(Justin) made 3 different doors for me till we got one that fit just right. It’s much lighter than the metal door and is easy to use. Despite the 3 try’s to get it right, I was charged only $25 one time. The door looks good and works easily. Justin was easy to work with despite the long distance between our states. I’m very happy with my door and am so glad to have my mail service resume.
