What kinds of information and insights did it give you about the useability of the prototype?

The information gathered was quite natural. It was clear what worked and didnt work. The limitation of this technique as it is quite a lengthy process to get one perspective of how one uses the processes.

What aspects of thr technique worked well or were frustrating?

Suprisingly this technique works quite well for the user. Though it is quite stressful making mistakes with people looking over your shoulder. The aspect which I had incorrect presumptions about was how natural the verbal component is while completing the task. I also feel that you understand the emotions of the user quite well through their facial expressions and bodily actions.
