I'm interested to read some reviews from anyone who's used this product. It seems to me that it has the same problem associated with any homemade dolly like a wheelchair or skateboard. If the surface your moving over is not smooth, then all those bumps and jitters will be captured by the camera. Also the camera is awfully low to the surface its riding on, which might be ideal if thats what you want. I can definetly see the benefit of using this product if you want to dolly across a table, countertop, or some other raised, smooth surface that could not accomodate a traditional dolly.
