Recently a user of our Half Mile Hailer reviewed our product on Youtube.
He uses it for street evangelism, and begins with a 100 yard test where it performs extremely well. In the city at quarter volume he could be heard 2 blocks away. With the volume at half level he can be heard completely clear at 100 yards.He says it "Definitely packs a wallop. If your looking for a good system for a cheap price that is light, easy to carry, durable and has the power you need to get over top of crowds and things like that then the Half Mile Hailer is definitely a good product."
