Chamberlain HD900D on the Small Door 

That opener is very smooth, smoother then my liftmaster for sure, love openers like these!

I love that growl when it starts closing.

That things smooth. Sounds amazing.

Nice video loved those openers

Man I miss my old whisper drive

Nice Video! Very quiet!

That’s my dream remote 😢

Here’s my good recommendation for you. How about racing the linear and the chamberlain in battery back up mode see which door gets to the open position the fastest, and then which door gets to the close position the fastest that be a cool video idea

Can you upload a video of a genie 3024 on the small door

Why does it beep when unplugged

How many miles on the van?

If you see a big door open that's my house
