Low cost perfect solution
Ok. Let’s face it that I know nothing about an alarm system. I have an ADT system and a construction worker accidentally broke this small sensor at my basement door. Well after 2 hours of waiting, 4 transfers, and horribly exasperating experience with ADT and so solution. I simply looked on the Amazon for something that looked similar to me and I found this part. The order arrived quickly, it was simple to attach, and it works perfectly. I’m still planning to change from ADT because it’s just terrible.

Cheap but functional
Cheaply made. Had them come apart while installing. Product does work well.

Works fine with ESPHome and ESP32
I wired one of these to an ESP32 running ESPHome, and set it up to monitor my garage door. Works perfectly!

Every single one was defective
The bag contains 10 magnet sides and ten switch sides. All the switches are supposed to be open when the magnet is away and closed when near. Installed a few and they weren't working. Opened every single one and the switches were all stuck closed. The magnets had no effect on the circuit whatsoever. To late to return. Waste of money.

magnetic door/window contact saved me a ton of money!!!
We have a popular alarm company, We lost a small magnetic on our bathroom window, we calledour alarm company and asked if they could just send us 2 magnetic's and they said, We will have to send someone to your home to install the small magnet. They wanted to charge me 70.00 dollars for the service. My husband said that was ridiculous and he told me to look up a magnetic on Amazon!!!! ""I love it""!!! I have fixed my washer and dryer 3 times and so many other things that i would not have found, if not finding it on Amazon!!!! ""Thank you""!!!! :)

Cheap but unreliable
These are certainly cheap enough. However, only four out of the five had ON resistance in the single digit ohms. One was very intermittent with ON resistance sometimes over 100 ohms. I only need three, so four out of five will work for me. I would not buy again. It's worth spending a little more for switches that can be depended upon.

It works!
The magnets worked and made my 20 year old alarm system functional again after the original sensor was knocked off during a remodeling project. Shipping was fast. Great experience.
