The physical devices are small, and quite robust. If the technology is implemented properly, it can provide a smooth experience for the end user. However, in my experience, the technology is often implemented by executives and or higher level instructors who tend to be older and less tech-capable.

I went to an enormous university, and iclicker made it possible for professors to visually gauge their students’ understanding of course material. I used iclicker to participate in class polls, gain attendance points, and answer questions. I loved that iclicker could create visual representations in the form of charts so professors and students could see where they respectively stood. My class size could get substantially large (300+ students), but with iclicker, my professors could still get a sense on the class’s overall progress and make sure that every student’s voice was heard through polls and Q&A sessions. iclicker is so simple and intuitive to use. One doesn’t have to be an expert on technology to figure out how to use iclicker (believe me, some of my professors were pretty old and they used it seamlessly).

Ease of use. Just log in and set up quizzes or polls. Then students can use their remote, computer, or smart phone to answer the questions. Teacher's can assign things for students to accomplish prior to class to assess knowledge. Students can review results and learn from questions they get wrong. You can have classrooms within iclicker for each course in order to keep things organized. There is a section for study materials and a place to see grades. The company has a very responsive help desk. They are polite and eager to ensure that their users receive excellent customer service.
