Review: Great quality sound from a little box. - I’m delighted with this system. Really easy to use and perfect for my work when outdoors. Long lasting battery and very good quality sound. Great range too. Small enough to carry on you or leave near by. I’m recommending this product. Great experience and really happy.
Review: Robust and long battery life. - Brilliant piece of kit. Has saved my voice as a supply teacher and means I can happily do a full day’s work with a class I’ve never taught before and not need the next day to recover. All teachers should be offered one of these at the start of the school year - it would revolutionise their ability to get on a do the job for hours on end, day after day without risk of straining their voice. This voice amplifier has completely changed my working life for the better and is probably the main reason I’m still working as a teacher.
