Quick story. I used to work at a music store. Preacher comes in to buy 6 wireless mics. My PA guy is selling him on some SM58 mics. This preacher comes back in for 5 days in a rwo asking all kinds of silly questions about reliability and specs that he honestly didn't understand. Finally my PA guy says "How about we make a deal? I'm going to throw this mic across the room and slam it against that wall over there. Then I'm going to walk over there and pick it up and say check one two. Then you are going to walk up front with me a ring up these stinking mics you have been bugging me about for 5 days. Deal?" Preacher agrees. PA guy literally FLINGS that mic up against the wall. Walks over and "Shure" enough it works great. All we had to do to the mic was screw another ball on it and it was perfect. The preacher even bought that one.
But, yeah, they are good stuff. Not the most amazing thing on Earth, but really good for the money. And road work horses. A good old SM58 and 57 ride in my gear box to every single show.
