Rated 5 out of 5 by from Better than I thought it would be. I bought this to replace an old worn out chain drive unit. The install went better than expected. The instructions were good and some of the instructions like putting a screwdriver in a hole to keep the trolly from moving when installing the belt are important. But once I read the instructions carefully everything went well. The ability to use your phone to open the door is the bomb. App works great and was way easier than I thought it would be. It takes about a full day.

Rated 1 out of 5 by from Junk Have had nothing but problems since I purchased it a 1-1/2 ago. Two weeks ago it would only close anywhere from 1ft. To 5 ft. so I unplugged it . I ordered a travel module and it came yesterday. I plugged it back in before changing the module and it started working fine so I left it alone. Now for some reason the lights will not stay off. Called customer service and she said it was a problem with my door and not the opener. Now I don’t know what to do with it.

Rated 5 out of 5 by from 1st Garage door opener I received the B550C as a Christmas gift. I installed in in my 20 year old garage that has never had an opener before, It was easy to install following the instructions with great diagrams showing tips that allowed me to do it by myself. Just needed basic tools. Programming was simple and only required pushing a couple of buttons for each device. The MyQ app allows me to see the status of the door and open/close it remotely. The noise level of the opener is less than the noise the door makes in the tracks. Love it, so far!

Rated 3 out of 5 by from Not too bad opener This opener is very quiet and smooth, and I love the programming feature from the wall button. I have had to re-program several of my remotes once and this made it a lot easier. Sometimes, the garage door will reverse when it gets a foot off the floor, and I can't seem to understand why. The key pad also has short battery life. Otherwise I love the MyQ and all other features of the opener, and how smooth it is.

Rated 5 out of 5 by from Easy to install and very quiet. I installed this yesterday. It was simple to assemble and a breeze to install. I used a YouTube video that was so clear and easy to follow. I have two others (three bay garage) and the others are worm drive. So loud. This is whisper quiet. I am so impressed that I will replace the older noisy ones with the B550. I love how it is integrated with MyQ. Makes setup a snap.

Rated 1 out of 5 by from Why Doesn't Chamberlain Give Better Info!! I have two garage doors. I bought the B550 unit to accompany the 2014 Chamberlain unit on my other garage door. I researched this website to find out if I could use the two together on one remote. The only info I could find is that nothing works on units older than 1993. Well, when I finished installing, I tried to program the remote that came with the B550 to work with my 2014 unit. It won't. Apparently my "old" 2014 unit is not compatible with my B550 remote and the only solution is to buy a programmable remote. So, in order to use both of my Chamberlain products, I need to shell out more money or haul around two remotes in both cars. This is information that I should have been able to find out before I purchased the product. Also, Chamberlain website needs to be improved. Especially the parts and support search functions. The don't work well at all.

Rated 1 out of 5 by from Waste of money! We paid extra so that we could use the app to control the door opening and closing, and it is ALMOST ALWAYS OFFLINE!! And it always says “OFFLINE” for 3 minutes or some small amount of time just prior to me attempting to use the app. How convenient, NOT!

Rated 5 out of 5 by from B550 with more features than I need - a good thing This purchase was an emergency replacement for another 16 year old Chamberlain (under another name) chain drive unit. Because of the longevity of the old unit and because I knew that many of the mountings would be the same as the old, I purchased this B550. I really like the quiet of the belt drive as compared to chain. The only problems I had were that the hole in the trolley to accept the threaded shaft was too small so I had to ream it out a bit. Perhaps it was just a little too much paint - and I did have a drill bit large enough to clear the hole. Also, the description on how to tighten the belt needs to be clarified. I could find no way to brace a screwdriver against the rail because the direction needed to tighten the nut causes the tip to move away from the rail instead of towards it. This was the only difficult part of the installation as far as I am concerned - and I did the installation without help. The unit lifts the door very smoothly, but it initially jerks the door when starting to close. Not sure why and may look into that further at a later date. Overall very pleased.
