Door Opening Sensor

I got this as a gift for my son's place, and it's been most likely a decent addition to his security setup. 😊 As someone who loves DIY, I appreciate the simplicity—just slap it on a door or window, and you're good to go. It's helped me feel more secure, especially when I'm not around, but I wish the battery lasted longer. I'd recommend pairing it with other sensors for better coverage. Overall, it's a solid choice if you're on a budget and want something straightforward, but don't expect it to do everything perfectly.
- Pros: I was incredibly impressed with how easy it was to set up—just stick it on and it works right away, no drilling or wires needed. It gives me instant alerts when a door opens, which is perfect for keeping an eye on things, and the alarm is LOUD, great for scaring off anyone snooping around. Plus, it works with my other smart gadgets, sending notifications to my phone, which is a real workhorse for home security.
- Cons: The battery life isn't as long as I'd hoped, so I have to check it more often, and sometimes the connection between the parts feels a bit finicky, not always reliable. It might not be the best for very large spaces, and the alarm volume can't be adjusted easily without the app, which is a bit of a hassle.
