I think there isn’t much wrong with the marketing, this bevel is definitely at the top of the charts in comparison to the other methods, as it succeeds more often where other fail. (This doesn’t mean that it can’t still fail.)
I think for some of you the meshes you showed you are kind of asking for miracles.
I’ve said this every time people ask for bevels.
A new bevel tool doesn’t solve the need to do work, it simply means that it can help out.
So yes, you may need to prep the model still, but at least after you prep the model you can get a nice bevel…rather than garbage.
