Honest option, as a customer viewing the videos.
1. The music needs to be removed. I was watching the videos and turned off the sound as I found the music annoying. In doing so I could have missed any information you might have given out over the course of the video.
2. I would have liked information to be given ( A voice over ), Telling me of what the process is and how your company's approach is better than say another one.
Not knowing how these videos will be used say maybe in conjunction with text or just as a example. More information the better. As a selling tool I feel your not fully utilizing it.
