A garage door opener needs to be completely and undoubtedly reliable, efficient, and quiet. It needs to be something forgotten, that fades into the background and never stands out. When it comes down to it, if a garage door opener is noticeable then something has gone wrong. Now, there are many openers on the market that are very noticeable, but a few that keep things dignified. These might not all be bargain basement units, but they will complete the mission of fading into the background completely. Chain drive garage door openers enjoy some advantages over their belt driven brethren, including generally lower cost, and higher lifting power. Even many heavier garage doors can be lifted thousands of times by chain driven systems, with barely a peep and never a slip.
