Hi, I was wondering how much less is a 30 to 40 db (Wind)-Noise Reduction ?? I am thinking about buying this product now, as opposed to in a later date. I am moving to a different country for a few months and it may not be as easy or accessible to get one of these later on. That's why I'll be trusting your advice. The zoom recorder will be used to conduct interviews most of the time inside a building/house, not outside. However, even for interviews indoors, you may still consider that this item is very helpful or even necessary. A disadvantage is that it is a bit pricey, even though people claim that "the quality is worth it". http://www.bhphotovideo.com/c/product/595000-REG/Rycote_055370_Mini_Windjammer_for_Zoom.html Thank you very much in advance, very kind regards, igmolinav : ) !!!
