I bought this mic and a deadcat wind muff. When I listened to the playback after filming, it still had the annoying wind noise. I couldn't figure out why. At first I blamed the deadcat, but then I realized it wasn't the deadcat at all, it was the back of the video mic where the jack input is. If you blow ever so slightly at the back of the mic even with a wind muff, you will hear the wind.
So, if they could seal up the back a bit better, this would be a great mic.
