I used this the other day in the free version. The text over the screen was annoying, and the background effect was rather glitchy, but it was effective at hiding the mess I was too lazy to clean up.
However, as we were using it for work conference, I felt like I was adding some goofiness to the call and didn't like that. I ended up moving the camera to show less mess, and then eventually actually cleaned up my mess.
I use it for a bunch of goofy stuff in meetings to lighten the mood. When I want to be serious, I change the background image to a photo of our office. If you combine it with OBS studio, you can overlay yourself on presentations or videos, which is also very useful.

Plus, VCam only works in Windows.
