I just wanted to say that I’m very pleased with the GabStopper. As a deaf person that is teaching sign language to my students, it is a frustrating challenge for me to constantly monitor the students’ talking. Far too much class time is wasted with classroom management. However, with the GabStopper, every single one of my classes has earned a score of 100% of no talking with GabStopper. Now, this might be a novelty that may wear off after a while, but the fact that ALL of my classes hit 100% even once is just amazing to me.
