Tried it twice and then it started stinking all the time even after repeated flushing. I didnt like how you could not see if the water was clear when flushing the black tanks......so I removed it and have a ton more room in my wet bay. Never liked the idea of sewage under pressure.
I use the Macerator 100% of the time. I believe it to be much easier to handle then the slinky and less messy. I have a hydraulic hose cover on my line to prevent wear on the hose and protection against any leaks. In addition I have added a 90 degree elbow so that the line has a straight shot down through the wet bay opening. That being said I carry a slinky system as a backup to any problems I might have with the macerator.(never have had to use it)
