Initially, I got this as a joke for my kids, as they tend to 'not hear' me when I call them from the gaming room downstairs. They heard me, this really caught their attention ;) Now I see that it could have many other uses, like at our camp while hiking or fishing away from the others, or sporting events and such. I do find the speaker part squeels really loud if its not far enough away from the receiver, but it doesnt catch your voice if its too far away either. Takes some playing around to get the right distance, but once you do, it does work loud and clearly. I will say that the fm radio works extremely well, better than any radio I've heard.
