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

Works great and fairly easy to install.

This works really nice if you're changing out an old Chamberlain

Price. After checking around for pricing, I found This Unit was $30. cheaper than Menards even with Their 11% discount, Plus I didn't have go get It. Installed in an Hour. Quiet operation. 2 controllers, wall mount switch, exterior security pad.

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.

So far it works great. The install was easy. The 3d animated instructions were very helpful and easy to follow. Hopefully this opener will last a long time.

Why did you pick this product vs others?:Works greatAlthough there are not any instructions for assembly. Use your old one as a guide to install this one.

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.

I like that I can use my phone to open and close it. It went up in about 90 minutes. I was hoping to set a timer to close it, but that feature is not on this model. I can set a schedule, but not a timer. I also didn't like feeling bullied into setting up an Amazon prime key.
