Worked perfectly.
I needed additional magnets so that I could open my window and still have my security alarm set. If someone would try to come in my windows while they’re open the alarm would go off and notify the monitoring system. Less expensive to buy a set than to buy individual magnets from my alarm company. I will be ordering additional sets for the rest of my windows. Thank you.

The magnet is not strong
Just need to replace a lost magent on a door sensor. The sensor would not detect the door close with the magnets that come with this package. I had to purchase something else.

Works perfect
After extensive searching for the right contacts for our alarm system. These worked just right as replacements for our broken, worn out ones

Not what I needed
I can’t really say if these are good or not. I mistook them for something else. They do not work for my needs.
