Any thoughts or reviews on Typmock for c++?

Hi, my name is Allen I’m new here.
I wanted to know if anybody had the chance to work with Typmock’s tool for c++, I saw on their website that it’s free for life.
Is it worth anything?

I’ve read a pretty good review on Quora and I wanted to hear your opinions.
Here is the post:

Thank you :slight_smile:
