Chamberlain C2405 MYQ Smart Garage Door Opener, Chain Drive, 1/2-HP Motor, Dual Light - Quantity 1

I just registered the product and chamberlain ask me to submit a review but i can’t find anyway to write a review on chamberlain website therefore come back to Amazon.It a good product and i can install it by myself without any help just print out the instructions and follow it. The only concern is the chain came either half chain half string and pulley made with plastic material. Hope it can last at least 10 years because the old one last 10 years.And luckily i bought this unit because my old remote only can program with liftmaster and chamberlain.So far it being operated for weeks without issue. Keyless entry work perfectly. But my old software door opener don’t work with it (a wifi garage door opener unit) connect to controller door oper connection but only hear the clicking sound but not reaction on door. ( smart chamberlain program prevent 3rd party hardware but too bad for diy customer)Overall is a good product like it

Went to shut my barn overhead door and it would go down and then go right back up. I called a local handy for help and he tried adjusting it but to no avail. He picked this opener out on Amazon and I ordered it. Got it in three days where from some places, an order takes 7 to 10 days. The handy man came out the next day and had it installed in about an hour. Works like a dream!!! Very happy!!

I replaced a 15 year old 1/2 hp Chamberlain LiftMaster chain drive motor unit, with this one. I purchased the unit from Amazon, and had a local garage door company install for a nominal fee. (I didn't feel comfortable replacing the motor unit myself)So, I can't speak to the ease of installation, or replacement installation... other than to say, it only took 30 minutes for the local garage door company's technician to replace the new Chamberlain motor unit + interior wall mounted controller + exterior keypad, & also programmed the new car remotes/controllers. All in 30 minutes.As part of that installation, the local technician used my existing single one-piece rail & full chain system, that was already in place from my older unit. He just replaced the motor unit as part of the assembly.Which brings me to my 2 star rating for "sturdiness" -- Before replacing only the motor unit, he explained to me that this newer unit... while it *does* come with a rail and a chain system in the box... the new unit rail is not a single, one-piece rail (obviously, based on the box size)... it's a rail system comprised of 5 attaching parts. Which could be more prone to failure, than a single one-piece rail system.Additionally, the chain that came with this new unit is a 80/20 chain system. It's about 80% of actual chain, and the other 20% is tied together with a steel thread. Which obviously is not as strong/resilient as a full chain system.The technician literally told me: "Your existing single piece rail & single piece chain will have a longer life than this new motor unit you just bought."For that reason... for "sturdiness" of the overall product, I ranked 2 stars.As for the motor unit itself... I am very pleased with it.- Installation was a breeze, if you're replacing an existing 1/2 hp Chamberlain LiftMaster motor unit.- It is MUCH more quiet than the previous generation of Chamberlain LiftMaster motor units.- This model has two lights, as opposed to a single light in my previous Chamberlain unit. It makes a world of difference.- The myQ app that works with your home's wifi is for the most part, very good. You can control open/close of the garage door from anywhere, and you can setup alerts on your smartphone to notify you anytime the garage door is opened/closed. You can even add "guests" to the myQ mobile app, so they can open/close your garage door... say, if you're out of town & they're taking care of your house/pets/etcThat said about the myQ wifi app, some "drawbacks" that I've noticed about the myQ wifi app:1. The myQ app does not have a function to turn on the motor unit's lights, nor engage the "lock" function of the motor unit... from the app (as you would using the interior wall mounted controller)2. The myQ app is VERY persistent about suggesting you to setup your wifi controlled garage door opener, to allow for Amazon deliveries. In the initial setup to connect the unit to your wifi, the phone app will say "setup complete" and then take you a screen that prompts to allow for Amazon deliveries, for Prime members. You have to close out of the app setup to decline allowing Amazon delivery access, without knowing whether it really is completed (it is).Some other notes:- This newer unit uses a different frequency than the older generation(s) of Chamberlain LiftMaster units. Expect to need: new car remotes, new interior wall mounted controller, new exterior keypad. Although our Chamberlain universal car remotes we bought 5 years ago from a local hardware store, they could still be programmed to control this new unit.- While the pictures of the interior wall mounted controller doesn't show it, the interior wall mounted controller DOES include a "lock" function (hidden under the fold-up open/close button), as well as a "light" functionAll in all, I am very pleased with this new Chamberlain LiftMaster unit.

The opener is great, although it was missing the following parts out of the box. 1) 041A6689 is a D-shaped threaded shaft. 2) Missing 2 of the 'master-links' for the chain. Luckily I was able to salvage all of these parts off of my 23-year-old Craftsman model that I was replacing and they were a direct fit. I also was able to use my existing wiring from my 23-year old setup, as it also utilized a red/white for the panel and a pair of black/white wires for the optical sensors. It also bolted right up and fit in the same mounting bracket as my 23-year-old model from 1992. All-in-all not a bad deal. I was able to obtain open-box for 147, which was significantly off full price!One thing I will mention is that you need to set the upper and lower travel-limits once via a combination of buttons on the back of the unit where the wires go. Once the upper and lower travel-limits are set then it works flawlessly.

1.30.2025 UPDATE: Door been working OK for about a month. Today though, we had an all day power outage, the battery did not work to operate the door. I'm trying to figure out why.Haven't gotten a lot of use out of it yet but it was easy to take down the old one and replace with this one, using the old rail and old chain. My 18 year old son did it himself and got everything programed to work in about 90 minutes. This was our first time messing with a garage door opener.Remember to cut off the red handle on the pull rope so nobody can break in by pulling it from the outside. If confused about this, google how people open doors from the outside by catching a wire on that plastic handle.Also remember you can still open any garage door without electric by using that same pull rope (if you have no battery back up). Teach your kids this too, for their safety in a fire or something.

Nice garage door opener easy to put up and it runs quietly.

Replaced old device. Very nice.

This was very easy to install. Directions are very clear once you scan the bar code and it’s step by step in your phone. Comes with plenty of wire for the sensors. You can link the garage door to your phone to open and close it from anywhere. It operates very quietly.
