### ⭐⭐⭐⭐⭐ 







  
  
    Works as expected
  

*by R***A on Reviewed in the United States on 3 August 2021*

We brought this product for our religious organization to replace an existing one by the same company of similar build.  Make sure you get the one with the right frequency you could check the company's website to make sure there is no interference from TV channels.  It was pretty much plug and Play for us and works well.

### ⭐⭐⭐⭐⭐ 







  
  
    Nice & clear! Easy set up with mixer. Be sure to get the right cords; either 1/4 inch or mic jack.
  

*by C***E on Reviewed in the United States on 23 June 2021*

It's expensive & I can't compare to something less expensive because I just went for it.
