### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Strong Performance for a low price.
  

*by B***S on Reviewed in the United States on March 17, 2021*

The Hollyland Mars 400S PRO has amazing tech for a reasonable price. Great wireless signal with very low latency and the ability to connect iOS devices has this device a class in its own. The app was used on two phones and still received a signal in rooms that had four walls separating the device and the transmitter. Transmitter has transmitted very strong signals from hundreds of feet away with no loss in quality. The 400s Pro is a must have for independent filmmakers!
