Any one have ever used the Cobalt MJ 900 pump was curious about the noise level? Trying to find a silent pump? I know it's a hard thing to acheave?

Thanks a million for the advise!
 
I've used it and it's silent as I can tell. I find the biggest problem people have with noise from pumps is when it's vibrating against something. I use my rubber feet and wedge a rubber or silicone wedge between pump and any walls it may be vibrating against.
