Very pleased with the microphone. Combined with Sony ICD-PX333M I did catch her with a sound quality very surprising for this price range. Very easy to use, no noise, highly sensitive and directional which is perfect for capturing the way to a narrator. Does not seem too fragile and the fastening system is correct. Perfect for occasional use quality. I have not tried it with a GoPro but with a dictaphone or pc no worries I recommend.
