However I own two of them (each with a lav & handheld mic) and have experienced nothing but practically perfect productions when using it with my VX2100, or any of my other camcorders. I've used the mics in a variety of productions at a variety of locations. My experience with far more expensive wireless mics has proven to me that they provide options I don't need. To start with, other mics are XLR for no real reason (except convention,) so they require a conversion from a balanced to an unbalanced input. The other compromise for cost is the limit of only two VHF channels. Should I ever run into interference, I'd be screwed (if I didn't always plan for disasters.)
Do not consider running a mic line to your handheld unless you have someone to stop people from walking between the camera & the talent. For all the years I've been doing this, if it is possible for someone to walk between the camera & the talent, someone will do it. And while they do it, they pay no attention to the ground and will trip on the mic line if that's possible. But so long as I'm at the camera, I have had success with putting the talent 6' away while using an 8' mic cord (so it actually hangs two feet from the ground.)
Good luck with your production and have some fun.
