Question about TwelveSouth BookArc V4

I have a Macbook Pro 16 inch and it fits perfectly. You have different rubbers so you can adjust it.

On a 15.6 inch 2018 MacBook Pro without problems in any case recommendable.

With a bit of patience, I can mumble my 16-inch MacBook Pro into it. But I wouldn't say it fits properly. It was a great solution for my 15-inch MacBook.
