This is one of my new favorites! It was an absolute lifesaver. I teach 2nd grade and have a lot of ELL and SPED students and masks make communication difficult, especially during phonetics. I started using the mic for my personal summer classes at summer school and bought one for another teacher. When I walk around campus, co-workers always compliment it and ask where I got this from. never had any problems with the battery. Although for this period it is very useful to use masks. I'll probably use it afterwards too. Save my vote!
