Review on Wireless Mailbox Alert - Mailbox Alarm, Briidea with 500ft Range, LED Light Flashing, and Sound Reminders by Brandon Reynolds

This unit works as advertised but getting it to work took more trouble than it should have. Getting the base to recognize the sender seems easy enough, but for some reason it didn't reset until I fully assembled it. I made several trips to the mailbox (100 feet each way) to open and close the mailbox door, then returned to the house to see if it worked. Eventually the reset worked and everything has been fine ever since. I think the instructions are missing a step or two. Now it works every time, and due to the holiday delivery crisis, my mail arrives well after dark, so I no longer have to make half a dozen trips to (not) get my mail. Note: The mailbox transmitter requires AA batteries. . The receiver only needs them in the event of a power failure. Otherwise, it will be disconnected from the household power.
