I have the SS and think it's the stuff. True that it uses more water and costs more but I like it. I usually leave the grey valve open and let it drain as it wants and just keep up with the black level. It doesn't smell after using and since it's mostly see-thru you can see your progress. Up-hill or down-hill, it doesn't seem to care. I have a plastic tub that holds the kit and while en route or storage itt sits in the shower tub. The back flush feature does pretty good - not a sub for the wand or installed sprayer. After watching a u-tube video I hadda give it a go. I've never seen another one in use but then I'm still kind of new to the TT lifestyle. I have my slinky stored in the bumper as a backup - hope to never need (it's the one that came in my "starter kit", ie: garbage).
