Got the wrong frequency for our area the first time; Got all static and no voice when it counted - make sure to check the manufacturer's website for your location! Exchanged it (no questions asked) for the correct frequency and it worked fine for our next wedding video. Range and quality are not what you get with high end UHF systems but it provides good value for the money and the sound came through fine. We even had a few "outtake" sound bytes to chuckle about. I'll happily continue to use it in lieu of trying to justify an expensive UHF system.
