The cleaner is made out of just hard plastic. The hardness of the plastic might make the inserting uncomfortable for some. Not really any give at all to it.
It looks like a big syringe with a plastic loop handle to push plunger part down. Hold 100 mil. Has 2 interchangable tips for cleaning: a short and a long one, both have hole for the water or solution to push through. Even with the lack of instructions it is easy to use and would work for most people.
Once I figured it out, it worked good for me. The hard plastic is a little uncomfortable, and I did need a bit of help because had no idea what I was doing. You can google safe enema recipies to find a solution, I just used a soap sud solution.
Clean with soap and water, and you will have to clean the holes in the tips thoroughly, to make sure you get everything out.
