Unlike the prior devices on this list, this is a full garage door opener itself, rather than an add-on device. With its quiet belt operation and battery back up, the Craftsman is a solid piece of engineering. Smart technology takes it to the next level, with an AssureLink app connection for your smartphone that lets you monitor and operate your garage door from anywhere with an internet connection. You can provide remote access to your home for family, friends, or deliveries while across the globe.
