Okay, so I finally got this Lancoon door alarm after reading tons of reviews. Here's my honest take after using it for a week!
First off - this thing is LOUD. Like, 'wake-the-neighbors' loud. The 105dB alarm definitely gives me peace of mind when I'm home alone. Intruders would probably run just from the shock of the sound.
The remote control is super convenient. I can arm/disarm it from across the room which is perfect for when my hands are full with groceries. The panic button is a nice bonus feature too.
Installation was stupid easy - just peel and stick! Though I did wipe the surface with alcohol first to make sure it stays put. Pro tip: take your time aligning the magnet sensor properly.
It's not just for security though! I use the doorbell mode when I'm working in my home office so I know when deliveries arrive. Multitasking at its finest!
For the price? Absolute steal. Way cheaper than those fancy smart home systems but gets the job done perfectly for my apartment.
