Great product
These are great! They appear well-made, were easy to install and work as promised! If you need new magnets for your alarm system, these will definitely do the trick - and the price - amazing!

Small, simple, and easy to install. Worked flawlessly.
These magnetic switch contacts worked great for my needs. The sensors are very small, simple, and easy to install. Just pop the cover off, connect the two wires, slip the cover back on, and then position the magnet nearby. The install took about 5 minutes, taking my time and testing along the way. Note that the magnets are quite strong, so when positioning the sensor and magnet, check the distance and how far apart they need to be to trigger the alarm. If you place them too close to each other, your door or window may be ajar before it triggers. In my case, I replaced 25-year-old sensors that were acting up, and these worked flawlessly, but I had to position the sensors further apart than the original ones. I can't comment on durability or how long they will last. I only installed them this week, but so far, they work flawlessly. They are a good value. The one thing I wish is that they included some two-sided tape because I cannot drill into my impact and window and door frames without invalidating my impact window warranty.

Used on a window connection for an alarm system.
Needed a simple window connection on an older ADT alarm system. These replaced the window contacts perfectly.

Doesn't work
Tried placing the magnet where the old one went and then gradually moved it closer until it was physically touching the sensor and it still didn't read as "door shut". Multiple orientations tried. Needs stronger magnets.

They work well as a sensor, but they are a little hard to open
These work fine as a door/window sensor. They respond to the magnet just how you'd expect. The only gripe is that the contacts for the sensor are inside and it's a bit hard to get it open. It's even harder to get it back closed afterwards.
