My boyfriend and I purchased the Big O Ring after a friend of ours raved about how great sex is with a c-ring. Being the ambitious couple that we are, we wanted to give c-ring sex a try, and so we surfed our favorite sex toy websites and happened across the Big O Ring. It ended up being one of two c-rings that we purchased. He slid the Big O Ring on his penis and turned the vibrations on. At first it was great. The vibration was strong enough for me to enjoy and the protruding nubbies felt nice on my clit. Unfortunately, the thrusting that is inevitable when having sex tends to make the Big O Ring come loose, so the vibrator turns away and starts vibrating on my thigh: not quite what I'm looking for when I'm having hot sex.

The material that the Big O Ring is made out of is a stretchy, gel-like material. It is soft, so it doesn't bother my man's penis, yet tight enough to make him last longer. When the nubbies on the vibrator are directed properly, they feel excellent when rubbing against my clit during sex.

While the Big O Ring has its strong points, it definitely is not without design flaws. The nubbies are excellent for clitoral stimulation, and they would reach my clit perfectly, if only the Big O Ring did not end up moving during sex. I would really enjoy this c-ring if it was one with double rings: one for around the penis and one for around the testicles. My boyfriend and I favor our two-ringed c-ring over the Big O Ring because we feel like the ring around the testicles holds the c-ring in place better, keeping the vibrator where it's supposed to be.

The vibrator has one vibration speed, but it is a pleasantly strong one. It is very easy to turn on, and, when aimed properly, does a very good job of providing clitoral stimulation.

The Big O Ring is very easy to maintain. After each use we just rinse it with warm water, spray on some sex toy cleaner, rinse, and pat it dry. We store it in a cupboard with our other gel-like toys to help keep the dust off of them, because jelly toys do tend to collect dust.

In our experience, my boyfriend and I have concluded that c-rings work better when they have dual rings. They simply stay in place better and make his erection last longer. Because the Big O Ring is a single ring c-ring, we rarely reach for it anymore when we're looking to have some c-ring fun.
