Easy to install and works fine
Very simple to install and they work just fine. There is nothing fancy about these and they are just simple, cheap replacement contacts that anyone can install. If you need to replace a few of these at your home you can easily do it yourself instead of paying an alarm company to do it for you.

Great Buy
These contacts were perfect. They easily fit my door frame for my home alarm system. Along with a quick electrical connection and I was good to go at an outstanding price. Plus I ordered them on Tuesday and they were in my mailbox on Wednesday US postal delivery.

Easy to install, works great
Had to replace a few contacts because lighting burned some of ours. These worked perfectly, easy to install. Would definately recommend.

Poor quality contacts
All my contacts were pre-wired during construction and insulated with 8" of foam insulation. Around 70% of the contacts will work sometimes and other times, no. Now, I have to rip wires in that foam to replace them with better quality contacts. Who would have thought you would have trouble with simple alarm contacts.

Easiest When There is an Existing Hole
Great Value... alarm service wanted to charge for a service call and probably $20 bucks just for one, when it's a matter of splicing two wires on one end, and the new magnet on the other, and then have some left over for the next time!
