BTT Manta M4,5,8P

Anyone using the BTT Manta M4,5,8P board? What are your thoughts? My wife doesn’t like how loud the Ender 5 plus is (apparently depending on where you are on the main floor, certain axis movements make it sound like the microwave beeping or the refrigerator alarm- LOL!). In the interest of keeping my wife happy… I ordered a Manta M8P with CB1 board for running Klipper.

I have not tried that board yet although BTT is getting really good in their quality control I would be interested to see if anyone else here has had the chance to try it.
