Before I got this, I was always worried about someone sneaking in, especially living in the city, and I'd check doors and windows constantly. Now, after using it for a while, I feel a lot more secure—it's like having a little watchdog that barks when anything opens unexpectedly :) It's not perfect, but for the price and how simple it is, it does the job well and gives me peace of mind without any complicated stuff.
- Pros: I was extremely impressed with how easy it was to set up—it works out of the box with no tools needed, just stick it on and it's ready. The sound it makes is LOUD and really grabs attention, perfect for keeping an eye on things without any hassle. It's great for my home, especially with a kid around, and I love that I can move it wherever I want since it runs on batteries.
- Cons: As it seemed to me, the adhesive might not hold up super well over time, and I have to remember to test it and change the batteries often, which is a bit of a chore. The noise is so intense it could startle me too much if I'm not expecting it, and I wish it had a way to adjust the volume or something.
