We were very satisfied and have little to add to what is already fully covered in the description and in the numerous positive reviews. I did make the mistake of arriving at night with intermittent internet on my dying phone, and not having printed out the instructions. Please remember, you need the code to enter the outside door, then the combination to the mailbox, and then another combination for the lockbox inside the mailbox. Luckily, I had saved Salome's phone number on my phone and before it died she very kindly led me through the process. 😁
