My O2 Revolution is hands-down my favorite dildo out of my O2 collection because of two things: firstly, the big, squishy head that hits my g-spot dead-on (probably because it's so big). Second, the glorious veiny texture on the shaft. I find I don't even have to thrust that deeply with it. Rather, sliding the head in and out gives a delightful popping sensation, which no other dildo I own can replicate.

The Revolution is made of Tantus's dual-density O2 silicone, which means that it's soft and squishy on the outside, but it has a firm core that keeps it straight and easy to handle. It feels more realistic than solid silicone, and it's a great toy for just about anybody, I think. It is bigger than most of my dildos, but because of the squishiness of the outer layer, it's much easier to use than if it were solid. Also, this is just a bonus, but I love the effect the blue core and white outer layer have. Because it's silicone, it has no odor, and it's completely non-porous and has no harmful chemicals.

I think the Revolution's design is a bit more exaggerated than realistic, but it still looks gorgeous to me. It's pretty darn big (7 inches insertable and 1 3/4 inches in diameter), but very easy for me to take because of the softer outer layer. However, this is not a beginner's toy. It usually takes a bit of warming up to get it inside me, but I think it's more than worth it. One thing that kind of irks me is that the Tantus logo is on the bottom of the base instead of the top, since I usually determine whether my Cush is upright or not based on the positioning of the Tantus logo. Also, this sort of goes without saying, but it's not remotely discreet.

The best part of this toy, for me, is the big squishy head, and it's really great for g-spot stimulation. The part I would have to take points off for is that, at least with my toy, the base isn't flat, but rather convex, so it can't stand upright after cleaning. It's harness compatible, but it's something of a challenge for me to fit the harness ring around the head, and the base isn't that big. I think it could've been wider and flatter, like the Cush.

The Revolution is really easy to clean with soap and water. ALso, since it's silicone, you can boil it or wipe it down with a 10 percent bleach solution to sterilize it. You shouldn't use silicone lube with this toy, because it can damage the toy. I recommend storing it in a plastic bag, because like most silicone toys, it picks up lint like crazy.
