I purchased the mzm 1 for a major interview, but it's worse than the camera itself. It claims that the rubber stops the motor sound. What's a flimsy piece of rubber band going to do? I have to look into other microphones like the canon dm-50. Please don't buy it. I know it looks tempting because of its price, but just trust us on this. I did several tests by changing variables such as batteries, wind socks, and zoom/normal, but it just doesn't work! If I could, I would rate it a zero instead of a one. I don't even understand why it got patented. It's nothing!
