LiftMaster 8550 Garage Door Opener Elite Series
ListMaster and Chamberlain are actually the same company, although they do market two separate lines of garage door openers. This is LiftMaster's top of the line unit, packed with features, as they say in the product's name. The DC motor is backed up by an onboard battery, allowing you to use the unit, even when the power goes out. It's belt drive, making it a quiet unit that won't disturb your family.
An on-board timer closes the door a pre-programmed number of minutes after it is opened for those times when you forget to close it yourself. Like the Genie unit, it has a lighted safety system, to reverse the motor is anything passes under the door while it is closing. It also comes with the same access system as the Chamberlain, allowing you to access the unit from your computer, tablet or smartphone. Additionally, both the motor and belt carry a lifetime warranty.
