I was just reading through the comments on your [H] thread, allot of people are suggesting that you need the case to have a video review by a tech channel to gain some campaign traction.
I agree, but I don't think you will have time unless you have already started this process and shipped the prototype out to a tech channel at least a week ago? I imagine that 20 days is quite a short time for a reviewer to plan, shoot, edit and release a video. It then needs some time to get watched by the public and for those views to then translate into sales.
If I were you I would concentrate on putting your own video together, even if its just one of your guys holding the case in his hand sat at a desk and explaining its features, maybe tied in with a section of a fully built and working system, perhaps playing some games with it.
Someone once told me - It takes the average person 14 days to purchase a high value item from the point of making the original decision they want to buy something new.
For example, you might get paid at the end of the month, that same day you decide you want to buy a new TV, you then research the market for a few days, have a think, change your mind, research some more, make a decision, take a few days to pluck up the courage or convince the wife. By the time you've actually made the purchase its the middle of the next month.
I think you need something to happen now, not near the end of the campaign. That being said, I wish you the best luck and I hope the campaign is a success, its a really nice case.
