We made a video to explain our product - what do you think?

I think it's a clever idea - it grabs attention - she's great... The photography is nice too.

Going to be hypercritical now... Few things that need a polish...

Some of her words - particularly at the start are a little run together, mumbled and whilst I'm English - the US audience might struggle to understand every word.
Throughout - her pronunciation needs to be a little more polished and less rushed perhaps (hard I know). It's super critical - but it may just help polish things up.
Also - the teleprompter seems to be slightly off camera - if you can get it over the lens - that would really help.

https://www.autoprompter.com/ was released last week and is amazing.

I can thoroughly recommend this teleprompter too: https://amzn.to/2uqIOtM

Another screenshot or two cut into the start (perhaps the old way of doing things - so users can see the difference?) plus the URL at the end could also help.

Hope that all helps. I love the concept.
