Observations about the mock up: >
 * two people had difficulty using the gripper
 * 3 second learning curve for those that //want to learn//
 * if buttons were located on the ends, the user has a more intuitive turning direction

 * Overall** (risks, concept, mockup)
 * Mockups only**

The presentation was clear and you spoke well. The first slide showed the concept but not its use. The specifications were not very specific or quantitative with the follow up slide showing relevant design but not customer or user issues addressed. The idea that function could now be forgotten is not a good one and this is what your presentation seemed to imply. The mockup did not work very well but you did seem to learn from it which is good. The idea still is appealing but the reality of making it work is now becoming more obviously difficult. If you go forward with this novel idea, you may want to focus on separate devices for different applications (door knobs vs jars of various kinds) because trying to do everything with one device may make it not work well enough for any of them.
