Well made, sturdy, easy to set up, and a great price.
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.

Amazing Mailbox Alarm
I purchased this as a replacement and was blown away with how much superior this is to the old one I had. It does have the base station you need to setup, and I have this farther away from the mailbox than I ever have.The setup was simple, just install the app on your phone. Only took me a few minutes to get setup. The device for the mailbox is pretty flexible, there are different options for how to mount it depending on your mailbox setup. This works with a bunch of different types of mailboxes. Mine is a standard side of the road mailbox where the door flips down. This device is VERY sensitive and I’ve never missed an alert (again my old one wouldn’t always register the door opened).You also have adjustments for the sensor to accommodate non-level ground or other anomalies in your installation. If I was critical about anything, it would be the instructions on mounting the sensor. There is an adjustment knob, which appears to allow you to adjust for uneven ground, but I couldn’t find anything in the instructions. Luckily it wasn’t an issue for me.Now some cool things.. the app gets a push notification from the base station when the mailbox is opened. The base station blinks red, you get an alert on your phone, and in the app you get a big red pop-up indicating the mailbox was opened. You have to press the little button on the back of the base station to turn off the alert. This means keep the base station handy. I really wish there was a way to reset it through the application. To be fair, there is an option in the app as to whether or not to flash red until you acknowledge it by pressing the button.The app is flexible, you can determine if you want an audible alarm, if you want it to sound once or until acknowledged. You can also change the sound it plays. 7 different options and multiple volume levels. Mine has barking dogs activated. As complete as this device is, I was a little annoyed that the sounds are labeled Tone 1, Tone 2, … until Tone 7. You basically have to play each of them to figure out which one to use. You also have the option of what type of notifications. The device was triggered, when silenced, or if there is a low battery.Finally, the base station is the generic X-Sense base station, so it works with their other security products (door open, motion sensor, etc.)Bottom line, this is superior than any other mailbox alert system that I’ve had. The distance and reliability is awesome! I love that I get alerts on my mobile device. If you are in the market, I can’t image how you could go wrong. Awesome device!!

It works great!
It works great. I wish I had invested in this product sooner. I love knowing when the mail arrives and the notification through app is awesome and the base station chime is loud and clear when Iâm home. No more guessing. Setting it up was a small challenge but I figured it out. The instructions were clear but after installing on mail box I realized to get it to complete the set up I had to bring the monitor close to the base station and simulate opening the mail box and after that I was able to mount it back on the door of the mail box and everything worked fine.

Works well, instructions horrible
This mailbox alarm is fairly easy to install, if you ignore most of the instructions. The manual shows buttons to press in the wrong locations and LEDs also in the wrong location.The button on the base station is on the side, not the top as the instruction say. The LED on the mailbox sensor is internal and cannot be seen without taking the sensor apart.That being said, it works well. The volume of the alert, as well as the alert can be changed. I keep it fairly low. An advantage of this alert over others is that you can get an alert on the app when the mailbox is opened. This is very useful as you can know whether or not the check the mailbox when you come home.If the instructions were more accurate, this would have received 5 stars.
