Chamberlain B2211T 1/2 HP Smart Quiet Belt Drive Garage Door Opener with Battery Backup

I replaced a chain drive unit with this belt drive and haven't regretted installing it. The electric has gone out several times and the opener work great with the battery backup. Would pay again.

No assembly instructions.

I bought this thinking a "smart" door opener would be compatible with Google Home. Silly me to assume, I guess. It's a fine device aside from that, but it is utterly fraudulent to refer to something as a smart device if it doesn't work with any of the major smart home systems. The other issue was the assembly instructions. There's no paper manual, you have to use a secondary app and follow video tutorials. This is useful in theory, but the tutorials left information out. They were also recorded by an AI voice generator, which reads too slowly and monotonously. It drove me crazy after several hours of listening to it. Does it work? Yes. Is it good? Yes. Has it been an overall pleasant experience? Absolutely not.

No instructions programing harder than it should not easy installaion

You would think a smart device in 2024 would automatically work with Alexa, Siri, Google, etc. But no, not this device. What kind of a company would put out a product labeled Smart and not have a work with Alexa? After spending $225 for a professional installer to put it in for me, I discovered it won't work with Alexa. I have to take it apart to return it. I actually bought it at one of the big homesites but posting reviews anywhere I can until this company gets the message
