your video has no sound, voice over or explanation _what_so_ever_. again... you built the thing, so you know what's going on. how am i, as a potential customer, suppose to know what this is and does. you can defend yourself til you're blue in the face but that doesn't make the video any more clear to a potential customer. I would suggest that you look at these other product demonstration videos for inspiration.

i'm not trying to be a jerk. you have most likely put an incredible amount of time and energy into bringing this product to life. don't let it fail because you refuse to take another day and demonstrate it properly.
