I'm really impressed with this little lav mic system. For a $120 bucks it performs exceptionally well. I've had no issues with range and or battery life or sound quality. Is it perfectly crystal clear? No, and anyone who expects that without dropping hundreds on a high end lav mic system is delusional. However there are easy things you can do in post production to make it better. I edit on Adobe Premiere Pro and all I do to clean up the sound is use the "denoiser" effect and set the noise reduction to -8 and voila, done. It takes literally 5 seconds and the result is perfectly acceptable broadcast quality sound for the projects I work on.
