If you're looking for a simple yet effective security solution, the EverNary Door Window Pool Alarm is a solid choice. I installed these on my patio doors after getting a pool, and they've been a game-changer for peace of mind.

The 130dB alarm is LOUD—like, 'wake-the-whole-house' loud. When my curious toddler tried sneaking out to the pool, the alarm went off instantly, giving me enough time to intervene. The magnetic sensor is super sensitive; even a slight separation triggers it.

Installation was a breeze—just peel and stick! No drilling or wiring needed. The adhesive held up well, even in humid conditions near the pool. The included remote is handy for arming/disarming from a distance (up to 50 feet), though I wish it had a sleeker design.

Battery life has been impressive—over 6 months of daily use without replacements. The low-battery beep is helpful, though it startled me the first time!

A few drawbacks: The setup instructions could be clearer (I had to YouTube it). Also, check local pool safety laws—some areas require non-remotely-disabled alarms. Not ideal for uneven door frames either.

Overall? For under $30/2-pack, these deliver serious bang for your buck. Perfect for pools, garages, or any entry point you want monitored. Just maybe warn the neighbors about test runs!
