THIS IS THE ONLY KIND OF OPENER I WILL EVER BUY AGAIN. SUPER QUIET. GREAT OPTIONS AVAILABLE. MY ONLY ISSUE WAS THE INSTRUCTIONS SHOULD SAY HOLD DOWN OPENER UNTIL THE GARAGE DOOR REVERSES, DURING THE SET UP OF UP AND DOWN MOVEMENT.

I posted a review of one that I bought on April 14. This one was a little easier since I didn't have any issues with the door installation. The installation was easy and the instructions clear. The unit that I received with this purchase was not quite as well constructed. The fit and finish were just a little off. Threads of bolts and screws were rougher and harder to get into place. The collar was a little different and had one less set of screws to ensure complete and secure connection between the unit and the torsion bar. Nonetheless, the unit works fine and had I not received a little nicer example of the product with my first purchase I wouldn't have known the difference. Still love the various functions and the operation. I'll be adding some additional accessories to this one just as I did the last one...extra wall control and a keypad. Also, it was easy to program my remote control unit for the first door to open this opener and vice versa. Just push the learn button. Couldn't be simpler. I think I'll be buying one more for another building on my property.

Bought this a couple of weeks ago. Mine was for a 9 x 8 insulated door with windows. The installation was pretty easy, just followed the instructions...until I got to the setting of the limits of travel. It was then that I encountered a problem. Setting the open limit was not a problem. When I tried to set the close my cables started to unspool. I called the support number for LiftMaster and the person had me conduct several tests and checks, all of which left him mystified. He also told me that these were not supposed to be installed by the homeowner and I should call a garage door installer. I walked away from the project for a few days and returned. I figured out the problem. The tracks were originally installed too close together. The bearings on the door were binding about 2/3 of the way to the top of travel. The same binding occurred when the door started to close. With a normal garage door opener the binding was not noticeable and overcome by the force of the chain and motor. However, with the Liftmaster the door would not travel on its own and the cables started to unspool. I reinstalled the cables, reset the torsion springs.
None of the problems I experienced were caused by the LiftMaster, the hardware supplied or the instructions. All of the problems were as a result of poor workmanship by the original garage door installer.
Once the existing problems were corrected, the LiftMaster worked great. I love the automatic lock, the delayed auto-close and the quiet and smooth operation of the opener. I plan on buying an additional remote and a keypad. I'm also going to buy a LiftMaster for the other bay in my garage and at least one other for one of the other buildings on my property.

Ordered lm 8500 for 10x10 doors. Easy install, quiet, efficient in space for mounting and allowability to use space where traditional opener would be in center of door. In addition, For the price it wasn’t much different than buying tradititionaI opener, hardware to support from 14’ ceiling, additional length kit for 10’ door, and brackets to support top of door. I bought the two pack, and although they only had one car remote per package each was simple to program for alternate door. Buying and shipping from Open Door was flawless.

I replaced a traditional Liftmaster belt drive opener that was mounted on the ceiling below our kitchen. The old one was quite loud when you would open and close the door, now this one is almost silent when in the kitchen. this new opener also opens up the Garage ceiling space for storage, and is cleanly mounted out of the way in the front of the garage.
It took me about 3 hours to install, including removing the old operator, cleaning up wiring, and adjusting the existing door to work with the new operator.
The only downside is needing to get power to the front of the garage instead of the middle of the ceiling, however Liftmaster does have solutions for this problem as well.

The door opener works very well, but what really impressed me was how easy it was to install. It took some time because of all the parts and wires that needed to be run, but the directions were so well explained it went together without a hitch and worked the very first time it tried it.

I installed this on a 12x12 insulated door with windows. It works great. Very quiet. And small. I wonder why all openers aren't like this.
With its innovative wall-mount design, the LiftMaster ® 8500W opens up possibilities by freeing up space overhead. Plus, it's fully equipped with must-have features including built-in Wi-Fi for smartphone control to a deadbolt lock for maximum garage security.
