The Digitizer is very low resolution, uses red laser (even lower resolution) and is affected by ambient light. The Robocular one (from the point clouds they uploaded on their campaign site) is very high resolution, and uses its own white light to get accurate color representation. Plus the Digitizer is WAY overpriced, every 3D scanner on kickstarter does better for less...

I'm a backer, and did a lot of research before backing, I can't wait to get my Robocular!!!
