Safety and Security Features
The Protector System safety sensors with Rapid-Snap brackets project an invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down. The sensing technology will stop the door from closing if contact is made with a person or object. The opener lights turn on automatically when the Protector System's infrared beam is broken. The Security+ anti-burglary technology assures a new code is sent every time the remote control is used. PosiLock theft protection assures that once the door is closed, it says locked. Use the manual release handle in case of power failure.

Whisper quiet and a straightforward install
My house came equipped with a 1992 chain-drive Liftmaster garage door. It was very noisy and finally stopped working a couple of weeks ago. So I shopped at my local home repair stores and shopped online and found this model to be the most economical choice for my family's needs ( had by far the best price).
I was intimidated by the install, so the box sat in my living room for a couple of weeks. After reading the comprehensive instructions, I realized that I could leave the old door sensors, wiring and mounting hardware from my former unit. My 8-year old son helped me string the belt (a 2 person operation for sure) and my inattention to detail at this step was the only holdup on installation. I can say to make sure the opener trolly is fully in the "closed" position, that is to say at the end of the opening rail furthest from the unit. We started with the trolly in the middle and the result was that the door would only close halfway. After spending an hour figuring this out, re-threading the belt with the trolly in the proper position fixed it immediately. With that exception, instillation should have been just over an hour - but definitely longer if not for using my previously-installed hardware and mounting bracket.
Since install, it has performed marvelously. Opens and shuts perfectly each time. The rollers on my garage door are louder than the "whisper drive" belt system. My wife is surprised when I walk in the house from the garage because she doesn't hear the garage door opening.

Good Directions and Easy Installation
I just purchased and installed this door yesterday. The instructions are extremely clear and well written. The quality of the opener components is high and installation was a breeze. I was replacing an older opener that broke and was able to reuse the sensors and door mount. It took about 90 minutes from start to finish and is very quiet in operation.

Chamberlain WD822KD garage door opener
DISAPPOINTED! We are a little disappointed with our Chamberlain garage door opener. We purchased it from Amazon.com. We installed it in a day to replace an existing opener (about 7-8 hours). Instructions were pretty good. However, we could not get the door to stay shut - kept bouncing open. We re-read the manual, followed the instructions, made the adjustments and still couldn't get it to stay shut. I e-mailed their tech support, got written instructions (pretty much what was already in the manual) and it still didn't stay shut.
So we called their 800 tech support number. Of course, we put it together on a Saturday, and there is no tech support on a Sunday and Monday was a holiday. How many people put their garage doors together on a Mon-Fri from 7 am - 5 pm?
So Tuesday evening at 4:30 pm we called tech support again. We got a lady who was very nice and friendly. However, she had us take the housing off the opener unit and take the belt off as she read all these instructions to us. Painful after we spent hours getting it put together and mounted on the ceiling. We didn't think the belt had anything to do with the problem since it worked well - just wouldn't stay shut. She gave the instructions to me as I repeated them to my husband up on a ladder doing as she said.
For some reason, the spring expanded and was caught on the trolley now and bent the inner trolley connection with tremendous tension on the unit. Now the unit was broken and unusable! She then gave us the name of someone who could come and install it at our expense. So she said she would send us the new parts - trolley and spring. However, it would take 7-10 business days. So, here we are with having to wait 2 weeks to get parts, having to take the entire unit down and start all over. My husband is very frustrated. We thought of just packing up the unit and shipping it back for a return of our money!! We have so much time and energy invested now, we will probably try one more time when the parts come - but without 800 tech support!

Chamberlain Whisper Drive
Ordered the Chamberlain WD822KD belt drive opener on Wednesday and using standard shipping (a few bucks more) received it on Saturday. It took my wife and me about 4 hours to install, test and program the remotes. The directions were easy to follow and the only glitch was the opener "overheated" during repeated testing for force, distance and safety. We waited the required 30 minutes and then finished the project. The opener is extremely quiet. Where our old chain drive opener vibrated the floor of the room above the garage and sounded like a vehicle was coming through the floor, the Whisper Drive has no vibration and is barely audible from that same room. Obviously I don't know how the opener will stand up over time (our Craftsman chain drive lasted 14 years) but other reviews indicate it is durable and has an excellent warranty.
