As far as security, this model's ahead of the game with high-tech anti-burglary coding and a keyless entry pad as well as two remotes with three programmable buttons on each one, letting you control a separate door, gate or light. The unit itself weighs 39 pounds, so installation isn't a terrible ordeal, though you'll want to inventory all the hardware you'll need for the job, since it might not be included. Chamberlain's got top-notch customer service, and the motor in this opener has a lifetime warranty. Can't beat that.--Kris Jensen-Van Heste

Content: This is not a review, but an advice. This motor uses a band to move the door not a chain. So you won't be able to grow the lenght of the installation so easily. I had to return them because of that.

Hope this helps.

Content: I replaced two 25-year old Sears openers because the circuit boards were fried and replacements were not available. I read all the reviews here and that convinced me to buy these units. I recommend you read the other review comments on installation very carefully. Some problems encountered by others were addressed in the instructions so read them carefully! For example, the issue of an eight foot verses a seven foot door is well addressed in the instructions! If you are replacing an existing installation you will need to blend the existing with the new components. One area I did not remember being reviewed was the initial balance of the door. I have an original wooden door with 2-150# balance springs. I decided to replace those and the lifting cables because the door was not balanced (i.e. does not go up or down at the half way open point). All of this took longer but resulted in much better performance of the opener. I had to mount the safety beam lights on the wall because the bracket would not let the door close. It took me the better part of four days to do the whole installation. But, my scope was bigger than just replacing the openers. In addition, I was trying to reuse old brackets to avoid drilling new holes in the door.

I also discovered that the bottom of one door was cut off so it did not close fully. After fixing that and putting new weather stripping around the door my garage is 20 - 30 degrees warmer!

One funny consequence of this opener. Our old door opener was so loud that you could hear it operating from any where in the house. Now you cannot hear the door and we have to 'announce' we are home so we don't scare each other!

PS 1)deliver was in four days and I could not find these locally so am glad I ordered from Amazon
2) This is Bill not Sally


Summary: Garage Door Opener - Swap Out

Content: Lets cut to the chase here - if you are in the market for a garage door opener, your search has ended, just add this to your cart and look forward to a straightforward installation and an all round excellent package.

Why is it such a simple choice? Here were my priorities when I purchased an opener:
1: Build Quality - Chamberlain has a great track record here and the unit is rock solid.
2: Noise - Mine is installed under the master bedroom and I leave home at 6am, so noise was an issue. Lets call it what it is, this is a garage door opener and it makes noise, but it is MUCH quieter than chain or screw drives
3: Features - Does everything I could want. I have two units and had no problem programming the remotes and keypad to work with both. Also, the lights are good and bright and the package contains everything you could need for a solid install.
4: Ease of install - I am a new homeowner so don't have a clue about home improvement. That said, I had no problem installing each unit on my own in about 3 hours. If this is a fresh install then you will need additional mounting brackets but you can get these cheaply enough from your local home improvement store.

Am I a happy customer - no doubt, this is one of few products that exceeded my expectations in every dimension.

What didn't I like? The wire which came with the unit was shorter than I would have liked. I have a large garage and routed the wire along corners to hide the wiring as best I could. The supplied wire just wasn't long enough and I ended up springing for some more wire for $10 or so.

What else? My door is 6 ft, if you have a larger door then you will need the additional rail extension which does not ship with the unit.

What tools will you need? I managed it with a drill, a sprocket set, a hacksaw and a phillips head screwdriver.
Summary: Hard to imagine a better garage door opener

Content: This opener is a significant step forward in this business.
It is indeed very quiet due to belt and spring buffer, a small and cheap addition, almost eliminate ugly buckling. Sectional rail is a great innovation. It makes shipping easy and cheap and provides installation flexibility. Wide range of accessories is also something that everybody would like. And all this is achieved for a very moderate price.
A fixed length of the belt is the only disadvantage. There must've been different lengths of belt available so that an installer could choose from for different number of sections or there must've been a kit provided that allows to change belt length according to number of sections used.
