I have used this brand numerous of times in church installs. I have not had one problem. Once channels are set you are good. Sound quality is clear and accurate and I would put beside any of the bigger brands. The mic is highly adaptable to high spl situations on stage with additional gain adjusts on the mic itself, which aids in eliminating feed back. With Sweetwaters 2 year warranty built into the purchase its a win for my customers, making room to put the added savings toward other audio hardware.

The good: Mics sound decent. channels are eas to change. Compact receiver.
The bad: handling noise. No battery monitor. Mute is way too easy to hit. Had several loud pops during last event (would change the freq, it wouldn't happen for a while then would start again) Strong singers would make it start cutting out.

I am a wedding dj and this mic system gave me nothing but problems. The microphone pics up the sound of your hands when you adjust it. I had frequent drop out and rf issues even when using from just a few feet away. I would not recommend this mic system. It is quite cheap, but you get what you paid for.

These mics
did the trick. No hissing paired with good sound.

The event I was going to use this at was canceled do to this pandemic. I can't really rate them though I showed them to Video engineer who been guiding me. I got these for use at outreaches and will serve there purpose once the outreach is reschedule.
