I use a squirt, and it has been very reliable for the two months it has been running
I love it. It is hot to the touch when it is running, so I wonder if there will be any issues down the line with the heat, but so far it is quiet and smooth. Highly recommended!
I have a repular squirt with a panworld/blueline 40hd. It has been running since Feb of this year with no probems. They are near silent. I can not hear it over the water flowing through it. I like it.
