Know when the mail arrives

Reviewed in the United States on April 10, 2025
Easy to install on my post-mounted mailbox. I followed the metal-mailbox instructions and it has worked well. Mail delivery times were erratic in my neighborhood so I wanted to know when the mail arrived. Has worked without any issues. Some other reviewers complained about fast battery drain but min...

Works great

Reviewed in the United States on March 29, 2025
I bought the package with the antenna but didn't need it despite the 100' plus distance between my wifi and mailbox. We have a double door mailbox and didn't like any of the mounting options shown by Ring. The double stick tape provided was very poor and it took quite some time to expose the glue ... Read more

Works as advertised

Reviewed in the United States on March 19, 2025

It may be helpful to note that we upgraded our router to the Netgear RS700 to handle the increasing number... Read more

Just okay. Works, but not the way I expected it to, and lacking features I was hoping for

Reviewed in the United States on April 2, 2025
It's ok. It does not come with the promised install kit, I could not install the antenna, I could not get it to link with my Echo Show, and I only get push notifications on my phone. For this it works ok without an antenna, but there are cheaper options out there that do this. I had wanted it to ... Read more

Reviewed in the United States on April 3, 2025
you MUST have a bridge or other hub for this to work. It will not work on rural settings (Amazon Sidewalk) with SOLAR CAMERAS. I have purchased the only items left with a bridge as I was looking for the cheaper way out of this, I really would like the functionality of the mailbox sensor, and it's al... Read more
