The O2 Revolution gives surpassingly excellent G-spot stimulation. Its big squishy head offers both the friction and size to give outstanding results.

It has a flared base which makes it harness compatible and suitable for anal stimulation as well, although I don't think its large size makes it suitable as a beginners anal toy.

The O2 Revolution is made of ultra-premium platinum silicone. It has no taste or scent. It isn't the least bit sticky. The head is somewhat soft while the shaft quickly becomes quite firm as you move down away from the head. There are raised veins on the shaft, but its the plush head that does all the work. The inner core is quite stiff, so it won't bend as much as most other dildos.

The Revolution is 7 1/2 inches long. The head is 5 3/4 inches in circumference. The shaft is 5 1/2 inches in circumference near the head, tapering to 5 inches near the base. It is only moderately phallically shaped.

The head is softer than the shaft, but not close to the softness of a vixskin dildo. The thinning of the softer outer coating as you move down the shaft allows the firmer pink core to show through. The base is very firm.

It won't stand up on its own. The base doesn't flare out very much and the shaft is not quite perpendicular to the base. I imagine this is so it will be at an optimal angle when used in a harness.

Subtle veins along the shaft can provide extra sensation. I don't notice them, but I don't insert more than half of it. I just try to keep its puffy head moving back and forth across my G-spot.

I've spent some time analyzing exactly what it is about the O2 Revolution that makes it so wonderfully effective. I've concluded that the magic in its design comes from the combination of:

-a puffy head that creates just the right amount of drag against your G-spot
-the fact that where the raised head meets the shaft is a ridge that provides extra stimulation
-its substantial size and firm core which allows you to put as much pressure as needed on your G-spot
-the fact that its big enough to block and stimulate the sensitive urethra area while its in use, thus prolonging and intensifying orgasm.

These factors work in harmony to incredible effect.

When I received the Revolution, I was in a sexual response slump. For weeks nothing was working for me. I was beginning to think that something was wrong with me. All that changed the first time I used it.

I thought "Another product that won't work, but I guess I have nothing to lose by trying it." Not only was I easily successful with it, but the results were incredibly intense and long lasting. No other toy has made me so aware of the contractions that occur during G-spot orgasms - contractions so intense that I had difficulty with inward thrusts of the toy. This is a statement about the Revolution, not me. Its the rare toy where I even notice that there are contractions. Truth.

I sometimes wonder whether I really squirt or whether I'm just peeing. But with the Revolution the contractions are strong and unmistakable, giving me confidence that I'm actually squirting. And maybe I don't care when it feels this good.

I believe the Revolution can help those who are trying to learn to squirt. I've heard that one of the most effective ways to strengthen pelvic muscles (a key requirement for squirting) is through orgasms. The intensity of orgasm that the Revolution gives could be helpful for those working on pelvic muscle health.

I don't think it feels like the real deal, but it certainly feels fantastic.

By the way, I never climax with a man inside me, yet I easily can using the Revolution.

Since its made of high quality silicone, its nonporous, phthalate-free, hypoallergenic and very easy care. Simply wash, dry and store when you're finished using it.

It can be sterilized by boiling or with a 10% bleach solution.

Just don't use silicone lube with it. This is its only disadvantage - having to remember this incompatibility.

It comes in a simple clear plastic box with minimal information printed on the outside. The box will not be useful for storage. I keep mine wrapped in a soft cloth.

I will definitely buy this toy again if something happened to my Revolution.
