All three rings have the same dimensions and differ only in color. They are suitable for virtually all 'normal' penis sizes and very stretchy. Thus, thicker diameter are no problem with the traction with increasing diameter of course increases.
The material is not as shiny and smooth as shown on the product pictures and becomes porous after some stretching also at a point or another. It feels slightly sticky. The Abklemm properties are good and the product does in the use of what it should.
I deducted a star because the product is not necessarily suitable for everyone. Due to the fact that the material is slightly sticky, is a use in people who do not shave their pubic area completely blank, hardly possible. Hairs are pinched, rotated and pulled out - not a pleasant thing. I prefer short trimmed hair, because I do not want to look like a baby and for me it is very difficult and often possible to use only under pain these rings.
Overall a very satisfactory product with above shortcoming. For me, therefore, worth 4 stars, but for the price you can hardly expect more.
