Excellent product and easy to install
Bought this Garage door opener in August 2020, only got it installed April 3rd. 2021, because the Garage was inaccessible due to storage and construction materials been stored. The installation took about two hours as is stated by the manufacture, also the only changes I made were to removed the old one and installed the new one, and centered the bracket above the door. The travel limits setting was also simple and straightforward, was completed in less than 2 minutes. When I purchased this item last year I was sceptical since this was the cheapest one in its line, I am very happy with the outcome.

    Much much better than chain drive
    Second review. Bought July 2020 when 28 year old opener started having lock up issues. Just installed this B750 Mar 2021. Well engineered and super quiet with DC motor. Excellent install directions. One person can lift the unit into place by connecting the door header end first, then lift motor unit onto top of step ladder. Hung motor unit using existing brackets from previous opener. Adjusting up and down travel is electronic versus old micro switch technology. Just wish the box it came in mentioned that pre 2011-2012 Homelinks need Chamberlain Homelink Compatibility Bridge 855LM, available from many garage door companies/installers.

      First GD install
      My very first garage door full install. It was easy to install and easy to connect to the app. I just finished so I may update the review. As of right now I am very satisfied. It is much more quiet than my neighbors.

        Chamnerlain Untruthful
        So I read the fine print on the Chamberlain box before I purchased it. “May not work with your auto Homelink without a special 30$ bridge”. So I went to the Chamberlain site where it said in bold letters “NO SPECIAL BRIDGE REQUIRED” That was not true and now that I am stuck with the unit, I read that a lot of people were lied to in the same way!!! This is false advertising as far as I am concerned, and just a way for Chamberlain to make an extra 10 or 15 %. I tried contacting them over 3 weeks ago and I never heard from them. Next stop,,, The better Business Bureau!!!

          Great features - bad sensor brackets
          The BAD: The mounting brackets for the sensors are too small and require extension brackets which are not included. The wires connected to the sensors are permanently attached and must be spliced if using existing wiring. Registration confirmation of the MyQ app to time I could log in was > 15 minutes. Several (4) bolt sizes requires frequently switching sockets back and forth during installation. The GOOD: Installation documentation includes lots of pictures and was fairly straight forward to install. The unit comes with two remotes, multi-function wall pad, and a wireless keypad. The belt drive system is VERY quite compared to the screw drive it is replacing. Setup of the unit open/close limits is done via buttons on the unit rather than switches on the rail. During operation the unit speed slows as it approaches the setup operational limits which results in a "soft" stop rather than an abrupt stop. This also helps reduce operational noise. The multi-function wall pad includes a motion sensor which turns on the units lights when you step into the garage when leaving. Programing the wireless keypad is quick and easy. The unit connects to a wi-fi router and with the MyQ app once registered allows operating the door from your phone. The app also keeps a history of operation and claims to will work with a number of other internet applications. Summary: Overall the unit is a good value for the features provided. If you are somewhat mechanically inclined and have the tools and multiple ladders installation is not too bad. It will still take 2-3 hours plus additional time removal time if replacing a unit. Buy the extension brackets or be prepared to come up with a creative solution. You will also need small wire nuts if you are using existing wiring.

          Incredibly quiet, easy to install, intuitive to program, and the myQ app control is the best thing I never knew I needed. Stop debating and purchase this opener - you won't regret it.

          The Sound of almost Silence
          After 13 years, it was time to replace our original chain drive opener to an Ultra-Quiet belt drive model. I'm not saying this was an easy install, but no fault of the Chamberlain opener, I had to engineer a few things to make sure I could attached it to the original header in the garage, and figure out the existing wiring, let's say it was "backwards", Red was White, White was Red, and despite that and the Texas heat I was able to install this with relative ease with the help of my 6'2" step-son. Overall from the opening of the box to programing our cars and setting up the opener on our WiFi it took a little over five hours, but that included several breaks to cool off and one trip to the hardware store to pick up a 2x4 and some 6" lag bolts. I wish I could included a video, this thing is super quiet, you can hear birds chirping while the door is opening. I would highly recommend.
