    Noisy
  

*by C***N on Reviewed in the United States on August 10, 2022*

The pump so far is doing its job.  The downside is it is really noisy compared to other pumps I've had.  I can hear the constant humming when I step outside to enjoy the weather and outdoors.  Other than that it's doing what it's supposed to do.  The longevity of it will be my determining factor as far as purchasing again when needed.
