Meh.  Doesn’t appear to work very well
I’m not sure if I was supposed to turn the water yellow, but I used it on my skin and the water came out clear on the other end. The sucking feature worked fine and almost better on the hard plastic tools versus the rubbery tool would kind of fall out whenever I would push it onto my skin so I’d have to hold it extra with my finger nail while I was using the rubber piece, the rubber piece is a lot more gentle rubbing on the skin, but the hard plastic piece stays on and it’s a little more rough but works better. I also used this on my friends oily dirty skin to see if the water would turn yellow and to my surprise,  The water did not turn yellow for him either. And his skin was very dirty and sweaty from a long day of work. So I kind of doubt the efficiency of this machine. I’ve seen other machines that turn the water yellow that advertise the same things.
