Within 15 minutes of attaching the tune talk, while trying to adjust the gain the little plastic widget fell right out of the tune talk thingy. I can't comment on the use of the product since I promptly took it back for a refund. It is so shoddily made that while it might be a great product WHEN it works, I wouldn't spend $60 on something that fell apart in jsut 15 minutes. I am a 45 year old woman, not rough on electronics, so I can only imagine what a student would do to this thing.
