Review title: Better than expected
Product review: The LiftMaster 976LM is simple to install and program. I use it with a liftMaster opener. It took longer to remove the Genie wired controller that I had previously. Programming can be done before installation while standing at the wall mounted push button. Took about 30 seconds. No ladder was required.The control requires input of your code to both open and close the door. This is because of the way garage door openers work in general. One signal either opens or clsoes the door. Think of this like your car remote opener with a code. You can set temporary codes that expire after a set time or number of uses to allow visitors access.What exceeded my expectations was that this unit can be programmed for 2 doors, each with it's own code. My wife and kids don't really use this feature, but it's great for me. HTH!
