We launched our first project: A Low cost Fast moving Camera Slider. Fully programmable, High Accuracy, Quality Anodized aluminum build for a very low cost.
For me, the page is a little too "raw". It's like something you'd show computer nerds/tech's rather than an actual backer who wants to see photos of it in action and looking nice.
Not sure you should have too many videos on the page. I couldn't see them due to my location, so photos are preferred.
I would suggest giving your backers a few more encouraging updates and getting them to spread the word a bit for you. Backers really like to hear from an engaged campaign creator especially if its a product they really believe in.
