Is my animation understandable?

Hi folks,

I am revamping my old landing page and part of that is introducing animation help explain my product.

You can find the animation here: https://lottiefiles.com/share/vtwetsu9

On the landing page, it will be side by side to the headline (similar to this):
https://screenbud.com/shot/7654cc53-9917-40f8-a979-ab358e42d620/image.png

My questions to you, if you have time:

1. Based on the animation, what is the product doing?
2. Is the animation too fast? Too slow?
3. Would the animation benefit from subtitles?
4. Any other thoughts?

Thanks in advance for your help!
