These microphones are working great for me so far. I have had them for a couple weeks, and I have had no issues with them. They do what they are made to do, and they do it well! Its so amazing to be able to move around the camera's frame and still have great audio from my voice. I plan to use these a lot from now on! So glad I was able to get my hands on these. Hopefully sometime I'll be able to make an in-depth video review on these mics.
