Choosing the right cock ring depends on what your needs are. If you're looking for something that provides a firm grip on the penis only, AND reaches well enough to stimulate the clit, the 4Us cock ring is probably exactly what you're looking for.

The material on this reminds me of a textured silicone. It feels nice, but isn't sticky. There is a noticeable seam on booth the inside and outside of this toy, but it is soft and should not be irritating.

The cock ring itself does stretch very well, providing a nice firm grip. If you or your partner's penis is smaller than approximately 4.5" (the unstretched circumference), you won't benefit from very much of the cock ring properties, but the receiver will still enjoy clitoral stimulation.

I, personally, really enjoyed the material because the slight texture provided a tugging sensation on my clit. Combining that with the light vibrations really made this a pleasurable cock ring for me.

The toy's shape was definitely well thought out as the clitoral stimulator on this is a nice length that should accommodate most women's anatomy. The bullet is removable, so if you simply wanted to just have a light texture there (a good idea for someone who has never experienced a cock ring), that is an option as well.

My concern about this toy is the small U shaped piece on that cock ring portion. I'm not sure what the intention was other than this is the part that primarily stretches. While the material is holding up and it does indeed stretch well, I can easily see this becoming a weak point and tearing eventually. My partner has also noted because this U area is much thinner than the rest of the ring. The portion of his penis it touches, is irritated after use.

This cock ring comes with Rocks Off's signature RO-80mm bullet. I've been curious about the bullet and I'm glad to see it is removable. The bullet itself is stronger than other bullets I've tried. It does come with one N battery, but I would have loved to see it be slightly longer and able to accommodate an AA. Battery issues aside, this bullet does pack a punch and travels well through the material.

I was hoping to be able to use this bullet outside of the cock ring, but was quite shocked when I noticed the tip has a seam; which has a very sharp piece of plastic hanging on it (it may be able to be filed, but I don't want to risk damaging it). Sharp plastic isn't ideal for sensitive areas like the clitoris.

The material is specially designed by Rocks Off to be more environmentally friendly than silicone. I was glad to see that the packaging is also recyclable, and it is clearly displayed on the package itself.
