Is there any way to truly protect VBA projects in Excel?

I'm aware of how to password protect a project, but I'm also aware that
I can purchase a utility for less than $50 that claims it will open any
password protected project regardless of password length or complexity.
Does anyone have any experience with this product or similar? Can they
really work as claimed?

The questions are academic rather than practical. I'd like to know, but
I don't want to spend $50 to find out if it really works and I really
don't have any interest in using it. I do protect most of my projects
and would like to think it takes more than that to break security. I'd
be much more interested in securing projects somehow that would take
more savvy than downloading a file and clicking through an interface to
break.
