I purchased this product in order to record the boards so keep an audio track, and also to focus on the debates and on people and their body / facial expressions, without having to worry about my notes immediately. The result is convincing when debates take place on a proper tone, however, when someone yells it quickly becomes inaudible, but overall, if not, the result is very satisfactory, even with distant people in a good fifteen meters. The associated application is well made, and complete, but not against working properly once the in-app purchase made, practical hidden fees that I find dishonest and for which I take a star.
