🚪 Enhanced SW351-MDA Magnetic Window and Door Alarm for Improved SEO Review

works as advertised. This device is loud. The slight downside is that this magnet is quite wide and doesn't quite fit in the jam.

Unbelievable! How do you ship such a product? Batteries cannot be removed, they are fully bonded and cannot be removed. Completely defective item!

I just opened the box and tried to make it work but unfortunately all the batteries are sulphated, I need to buy batteries. For the future Please change the packaging and don't put the battery in the sensor.

I bought a dozen of these for my mother's house and installed them in April. A few months later I checked them and they are all dead. Replacing 4 batteries in 12 alarm clocks costs over $120. For that amount I could rent a professional monitor. Dumb things have a light that blinks every minute, which drains the batteries. I have another brand at home with no flashing lights that work for years without changing batteries. In addition, the batteries are hard to come by, they are so densely packed
