I bought this camera (which is a lot more expensive than much of it's non-gopro competition) specifically because the description says "External Microphone Supported" which is a feature I want, so that I can record sound from a different spot than the camera is located.So I ordered the SJ6 Legend, and a 4.5 star reviewed USB mic that fit's the mini-USB (not micro) connection. When I get it the microphone doesn't work. The camera clearly recognizes something is there because it cuts off the built in mic, but the external mic produces no sound. I confirm the mic works by plugging it into my computer, and then contacted the seller, where they informed me that the only mic that will work is the one SJCAM produces, which is not only more expensive and clearly lower quality than the one I bought, but only has a single 1 star review.Otherwise the camera works relatively well, but I am upset about spending ~$70 more than I had to just to not get the functionality I was looking for.Instructions are also quite lacking, but the camera is easy enough to operate despite this.I think 3 stars is generous.
