Door opens with cellphone app, the control panel, and the remote. Quiet and easy to install.
Chamberlain B4603T is much quieter than old traditional chain opener. I liked the myQ app very much. You download the app and it shows detailed animation and diagram how to install guide. I think you could install it yourself. It was compatible with my old garage door(lift master security +), so no need to replace the railing nor bracket on the ceiling of the garage. It has high quality build and strong horse power to work with 2 car garage door easy. It is wired to the house electric, so no worries for battery. You can download app on your phone, and open the garage door while you are on a vacation far away from home when Amazon delivery drop off your important items. It also came with 2 remotes which you can keep inside your cars. I got a control panel installed outside, and you can open by putting your pass cord. It works really well, and I am quite happy with this purchase.

Very quiet and smooth. The light disappoints somewhat.
I’ve installed a number of garage door openers in the past so I found the installation fairly straight forward just using the enclosed installation manual. However, the built in LED light didn’t work. In looking through the manual under ‘troubleshooting’ the instructions for addressing this were not at all detailed (see the photo). In looking at the opener it’s not at all obvious either as to what needs to be done “to remove the cover”. I reached out to Chamberlain customer support and they were very helpful. They ended up sending me a new light assembly (which encompasses most of the bottom of the unit, see photos). Included with the new light were more detailed instructions on how to remove the old light assembly. After taking out the screws and lowering the old light assemble, the wire connection came apart – clearly they weren’t connected tightly in assembly. Connecting the wires fixed the issue and I have an extra LED light if the original fails. By the way – if you need more detailed instructions on removing the light assembly do a Google search on the part number: 041-0203-000. From there, click on the chamberlain link to the part, which has a link to the instructions. As to how the opener works: I love it. It’s very quiet and works very smoothly. The MyQ app was fairly easy to setup and works well. The light though is somewhat underwhelming, at least in my specific situation, in that it shines on the back wall of the garage. My door to the house is on the side wall, more towards the front of the garage, so there’s not a lot of light that shines on it. I think having an adjustable light (one that could be pointed to where you want it) would be ideal. In the end, I’ll give this 4 stars: Great mechanicals, very smooth and quiet but the light is a bit of a disappointment. Edit: I was able to rotate the light 180 degrees and have it point to the garage door, thus better light the entrance to my house. See the last picture. Much improved, will up to 5 stars. Chamberlain should outline the steps for this in their manual!

Great Machine that I Installed Myself
I was able to install this machine all on my own! I will say that it took a while, but the instructions were very clear with each step along with way. The machine operates very quietly and I love the brightness of the light in my garage! It is also nice to have the phone feature when I am away. I couldn't be happier with the purchase.

Great very quiet garage door opener at a reasonable price
The garage door opener is just as they presented it. It was very easy to install, works great and is very quiet. It’s great .

Quiet, Compatible with Amazon Delivery
My previous garage door opener had a recurring issue with the chain jamming so I replaced it with this one. It's very quiet and works well. MYQ means it can work from your phone over wireless networks so you can command it to open before the house is in sight. It also means that it can be used with Amazon deliveries so packages can be left safe in the garage instead of on the porch. I was a little hesitant to allowing access to my garage but I installed with a MYQ compatible camera and MYQ door lock to alleviate my security paranoia. The camera records the garage as the door opens when the Amazon delivery driver uses a one time delivery code to command the garage open. The lock on the door to the house will self-lock when the driver sends the code to open the garage and then will unlock again after the garage has closed. I can see all this happen on my phone and have alerts sent as well. Basic MYQ functionality is free but storing videos has a subscription fee and is necessary if you want to actually catch the video in time (starting the app, selecting the display, and the video beginning to stream). There are versions of the garage door opener with a built in camera. I paid to have this installed by a local company I used before and the install price was reasonable.

Private equity meets legacy corporation strikes again
Just spent an entire day taking down an old garage door opener and installing this one. Kind of a pain in the butt because of my low ceiling, but doable. Plug it in though: no power to the sensors, no power to the corded opener. Awesome. Private equity meets legacy corporation strikes again. So I dial an overseas call center and she knows exactly what's wrong (almost like this happens all the time). She says I can either dismantle the entire thing for an even exchange — no kickback for the trouble — or she can send out "the brain" of the unit and I can install it myself. So now I'm basically manufacturing my own goods and services. But I'll have to wait 10-14 days for the part to arrive, of course. I'm sure everyone else sees it too, but if you're replacing a 22 year old thing with a newer thing the difference in manufacturing quality is blatantly obvious. It's too bad the previous homeowner took such bad care of the existing opener because it probably could have kept going for years. This one I'll be shocked if it makes it past 5, even after I have to manually replace a defective yet important component right out the box. Everything feels and looks cheap. But I don't want to take it down and waste another day with another unit. So whatever. Also knowing Blackstone's in charge of Chamberlain now, I definitely won't be buying any of their products ever again simply because of that. Had I not went to Google for their phone number I probably never would have seen that headline lol What a shame.
