### ⭐⭐⭐⭐ Satisfied
*by M***R on January 1, 2026*

It’s works as advertised and has decent sound quality for the price range. Clipped it to the bottom of a monitor and it is still there one month later without slipping. I wouldn’t normally recommend this use case, though, because of the short length of the USB cable (unless there is USB pass through on the monitor or the PC is directly behind the monitor). Loses a star because the power LED is bright and distracting and can’t be controlled.
