Your general opinion of this product.
I bought this to serve as a PA system for the athletics at a Scottish Highland Games. I'm never more than about 30 feet away from the athletes, 75 feet from the wireless antenna/speaker and the audience is anywhere from 15 to 75 feet away from the speaker. I needed something that would run all day on a battery (no electricity on the field) and be loud enough for me to be heard about 75 feet away, maybe 100 feet. It needed to be *Extremely* portable, as one of our events take place in a separate area, 150 feet away from the main competition area. This unit from Samson fills the bill perfectly.
