Long distance reception.
Works at about 150 feet, through the yard and into the house. I use it as an alarm for a shop door.

Very Easy To Use
Requires minimum signal to operate. Notifications are strong and no false alarms. It is in my front yard Free Library on the door. People have been stealing all the books at one time. It notifys me everytime the door is opened. Adhesive is aveage, I used super glue on the door piece and velcro on the transmitter. I recommend this sensor. The App is easy to use and you don’t have to pay for standard use. And the battery life is great… months at a time. Still on original one in Oct.

Simple, but effective
Pros: I recently got to test if this would work from a whole other state which I was worried about and the alert response time not only worked but was on time! There are times it gets a little delayed or the time and dates don’t match the alerts but I find that I just have to open the app every once in a while to get it synced up and working perfectly again. I haven’t figured out how to add it to my Apple Home app but for my needs it doesn’t really matter. It says you have to scan the barcode to do that but that isn’t working for me but honestly I haven’t given it much effort. I set it up without having to read the instructions cause it was so simple. The alarm only works if you have your phone ringer on, which mine is always off but the notification on silent is enough for my needs. The few times I’ve had my ringer on, the alarm is a nice touch and draws attention. I haven’t had to switch the batteries on it yet and I’ve had it for maybe 4 months now.Cons: the adhesive it came with doesn’t last that long. The adhesive lasted probably around 2 months and then randomly fell off the wooden door in the middle of the night but the device seemed completely unharmed and still works the same. I switched the adhesive for a much stronger one and absolutely no issues since. I’d probably start with a stronger one from the beginning.

Unreliable notifications
In theory, this product is fine – it does what it’s supposed to do… kind of. But the execution is all off.The good: you open/close the door, it notifies you on the app via a push notification.The bad: you’ll get a notification sometime between 2 seconds and 30 MINUTES after the door is opened.I purchased this so that, as someone who lives alone, I would be alerted if someone enters the front door while I am not paying attention, or so that I could walk my dog around the building without having to lock the door. A notification 30 minutes (not exaggerating here – literally 30) after the door is used is pointless to me. It’s actively unhelpful if, after I’ve come in for the night, gotten ready for bed, and am just starting to drift off, THE NOTIFICATION FINALLY COMES IN AND WAKES ME UP.Trash tier product. I neglected sending it in during the refund window so I am just throwing the item in the trash. It “does not spark joy” by a large margin.Extra demerits for dishonest documentation that verges on industrial gaslighting. The company says something like “there may be a slight delay in notifications if your wifi is slow.” If the range of delay was 1-3 seconds, I could mayyyyybe think that on my blazing fast wifi with 1Gbps internet, something on one of my devices was hogging the bandwidth for a moment. But in actual fact (as a former network engineer) this is like the company making a frying pan out of particle board and then writing “if your food is full of wood chips, you probably live in a construction zone.” The problem is not the wifi, it’s the manufacturer’s network infrastructure/design, so if you’re in this boat also, don’t let them convince you that you’re the one with the problem.

Great knowing when a door was opened!!!
I have installed on 2 doors and I like the performance I get alerts instantly and I can review the history on when they were opened and closed. The sticky pads all failed so I recommend using the supplied screws they work great and very small.

Cheap, but that’s it.
Setup was easy with the App, and it did work.However the whole unit is very slow in detecting when the door is opened. The fastest I got was at least 5 seconds after the door was fully opened, but most of the time it take about 10 seconds for the App to tell that the door was opened. Other door sensors I have tried takes less than 1 second to update the state in the app.Also the sensor’s smaller part (the bigger one is with the battery etc, the smaller one is either a magnet or so) is too narrow. It was really hard to attach it to the door with the sticker provided. I dont know how long it will stay either since the double sided tape felt really cheap. I have used other sensors like this for which I used 3M’s VHB tape which really stays put after long repeated uses. This one, I doubt so.

These are an excellent way to alert to an open mailbox!
I really like using these inexpensive sensor alert switches on our gates and mailbox. Our mailman has a wide range of times that he shows up each day so when he opens the top of the outside mailbox I get a *DING* on my phone so I don’t have to check over and over to see if anything has come in. These also work great on dog doors and on an outside shed to alert us when the racoons drop by to scrounge around.The app is easy to set up and both sensors have a nice, solid feel to them. I’m using them inside and outside (not in the direct rain) and both of them look like they’re going to last a long time.Recommended.
