Review on Honeywell Ademco 958: Advanced Overhead Door Contacts for Enhanced Security by John Young

My alarm company installed the wrong door contact for my garage (plain plastic door magnet on my top door). After the plastic fell off I decided to buy it as a replacement. Easy to install and reassemble. (web search). Sturdy and well built all weather construction, just what I really need for a wet and dusty garage. I've had no problems with the unit since installation and it saved me a service charge from the alarm company.
