Garage door openers are electronic devices that can let you open and close garage doors with just a flick of a switch or just a touch of a button. This technology has surprisingly been around for quite some time already so the technology has had a long time to progress.
There are various types of door operators. Basically, they can be separated into two types today: the remote controlled operators and the traditional electric opener.
