Feels too long. After about a minute I got the point and skipped to the end. The site seems easy to use, so I don't think you need such detail. If users are having trouble learning how to use the product, consider splitting up the demos into multiple videos so I can watch short segments.

The script felt very wordy. The words and screencast should compliment each other, but they felt very duplicitous here. I'd cut out 30% of the voice over, allowing the video to get the point across. My favorite resource for learning how to be concise is "On Writing Well" by William Zinsser. Check it out.

The background sound is very distracting.
