X-SenseSmart Mailbox Alarm, Wireless Long Range Mailbox Alert, Mailbox Sensor with SBS50 Base Station for Delivered Mail, SMA11

Every time I purchase an electronic device I shudder. Because it never seems to go as smooth as it should when I try to install it. Not this time!! It came quickly and I let it sit on my desk a couple of days because of my past experiences. I decided this morning to go ahead and give it a go. The instructions are step-by-step and very easy to follow. I had it installed and up and running in about 30 minutes. For me that's a record!The range seems to be really good. Our mailbox is about 40 yards from the house. I put the monitor in the nearest room to it, down on the floor, and it has worked flawlessly with all of the testing I've done. And I really like the fact that I get the alert on my phone and can set whatever alert tone I want.Today is day one, so I cannot comment on durability or longevity. But if the build is any indication it will last a long time. But for the price, features, connectivity, and ease of install? If it goes a couple of years I'll be happy and just replace it with an identical unit.

I tried the RING mailbox sensor and did not like it for my purposes. Primarily, it did not work with my Amazon show, so it only gave me notifications on my phone, and I could not customize the sound so it sounded like all the other neighborhood notifications. X-Sense comes with an indoor device ("base station") that makes a unique ding and has a red light AND you get a notification on your phone as well. You can easily reset the indoor device to its blue light by pressing a button on the device.PROSeasy to set up.works great with no special antennathe mailbox sensor itself is small (inside of the door near the top suggested) and does not interfere with the mail.you do not have to answer the telephone notification (and it asks you to do that on RING which is annoying).the base station comes with the sensor and allows flexibility to add more sensors -- I am particularly interested in a driveway sensor and the smoke detector sensors, and they are reasonably priced.CONSnone so far. I would have liked to have it say "you've got mail" but none do this!! LOLI am very happy and recommend highly!!

According to Google Maps, the sensor and base station are 100' from each other, though it's probably a little less (I did some manual measuring but did not want to run my reel tape across the street). Please see the associated picture for my setup.The base station is in my garage on large, cluttered steel shelving, and we have a metal garage door and stucco exterior. The mailbox is also metal, and although the company recommends installing the sensor on the outside of a metal mailbox, that's unreasonable if you think someone might be stealing your mail since they could just slide the sensor right off. So I installed it inside the mailbox.Part of the reason I got the sensor was neighbors complaining about their mail being stolen, but using "USPS Informed Delivery" I can see what I am expecting each day, and an alert from this sensor lets me grab the mail as soon as it arrives if I'm home. It's only been installed a few days but so far it has worked 100% of the time (as confirmed by my own testing and Ring cameras which snapshot every 30 seconds).My mailbox was here when we moved in, and it's a bit unusual. It has a swinging top portion and a locked lower portion. When the mail is delivered, the top portion opens enough that mail can come in, but not your hand, since there is a metal guard that also flips up. I installed the sensor on the lower, inside portion of the metal flap, so it does not block mail delivery (again, see photos), but that means there is always one or two layers of metal between the sensor and the outside which I was afraid would block the signal.In fact, I previously purchased a Ring mailbox sensor that never successfully alerted me to any mail. It triggered in a few tests, but was never reliable inside the box despite the huge antenna. One reason I bought the X-Sense was the separate base station, which could be closer to the mailbox than the Ring Bridge. Ring only lets you have one Bridge, and moving it to the front corner of the garage sacrificed the connection to the lights at the back of our property and still didn't detect the mail. Now the Ring Bridge is in the back of the house, and the X-Sense Base Station is in the Garage.The Ring Sensor might have theoretically been able to trigger cameras that would record who was accessing the mailbox, but since it never worked at all, it was a moot point. On sale, these units cost about the same (even with the X-Sense base station included).The X-Sense is also smaller and easier to install as well as being more effective and reliable.Contrary to another recent review, the app definitely works on Android. I am using a Pixel 6a (2.5yrs old at the time of my review) and it has no issues. Perhaps the other reviewer had a phone that was limited to an out of date Android OS. I am on Android 15.All in all, 5 stars! It even came with two adhesive pads for the backer. My only gripe is that has a two minute delay after triggering before it will trigger again, and I'd like to be able to adjust that timer, but I understand the reasoning.

I just installed this yesterday in my metal neighborhood cluster box. My house and the base station is about 100’ away. I chose not to follow the directions, which say to mount it on the swing open door. I was afraid it would fall off and get lost at some point. Instead, I mounted it on the back wall of my mailbox. It works as long as the mailbox isn’t so full that it blocks the motion sensor.I don’t use the base station’s alarm or light or announcements. I only cared about the phone notifications, which it does well.PROS:- Simple installation worked right out of the box. Super easy.- Can share the device with my neighbors so they get alerted when the mail arrives, too. (Untested, but seems straightforward)- Battery strength indicator, and battery low alerts so you know in advance when you need to replace them.CONS:- No signal strength indicator to know if you’re too far away or in danger of losing connectivity.- No way to temporarily disable alerts, so now it alerts when I get my mail as well. I’d like to tap a button in the app to mute it for 5 minutes or something so I can get my mail unannounced.
