Bought for Preaching, works great.
Bought this megaphone for preaching, as opposed to the other $200-300+ megaphones. This one cost me I believe nearly $140 with the shipping, and it works great. I needed a megaphone, because at the moment I had only owned an Aker AK38, which works great for a smaller and more quiet crowd, but not for larger crowds, roads, or noisy places like bars or concerts where the belligerent are yelling and music is blasting... I do recommend however, getting another strap as the one that comes with it is a little on the short side, but the strap does work. The build quality is also very good, in my opinion. But yes, if you don't have 2 or 300 dollars to spend on one of the other name brands megaphones, like a Toa for example is well over $300, then this is definitely a great choice. God bless you all -Dominic
