The O2 Revolution is a thick tool! It can be hand held and used as a dildo, if you can take a circumference of five and one half inches anally. It has a flared base, a thin flared base, however. This dildo is so big and thick, it cannot stand up on its own; it topples over.

It has no suction cup ability, but it is harness compatable. I was able to fit it through Aslan's Prince (vegan harness), and the Jaguar. It also made it through the Spare Parts Joque. It's a soft dildo, so you have to help insert it manually. It's not like an 18 year old's poker stiff rod. It's soft enough that you can thrust like no tomorrow, and probably not bruise your cervix. It feels soft and sensuous and skin like.

Tantus brags on its plastic see-through carton, that the O2 Revolution is 100 percent ultra premium platinum silicone. So for your body, that means no allergic reactions from their product.

It's a soft, juicy material. I have the blue, which is very pale, and it's gradiated down to a milky white. The cock has a very large bulbous head, and an extensively veined shaft for maximum sensation. It is quite an object of beauty.

There is no odor to the material it is made with. Being silicone of the highest quality, it must not be stored next to other silicone toys. The plushy texture feels like it could tear with force. It's not as solid feeling as some silicone toys, it's not rubbery or jelly like at all. It feels quite vulnerable despite its great size.

I find the O2 Revolution to be a gorgeous, almost icy looking cock; like one of those ice sculptures that's beginning to frost over. It's seven and a half inches tall, seven of which are insertable due to its thin base.

It has a bulbous head, heavy veins, and its circumference is 5 and a half inches in diameter. I had to insert this slowly, and with a lot of water-based jelly lube. It totally filled me up, and it was a very slow insertion. This is the thickest dildo I have ever attempted. It was soft and gentle, and once in was absolutely marvelous to contract against. I mean, you have to really feel it, the texture is something you want to constrict your muscles around. I think I am in love.

I was able to put an extra large Magnum condom over the dildo as well. My partner did not enjoy the "stuffed" feeling. She also thought it was too soft for her. (So it's all mine!)

It's not a discreet toy. It seeks its own attention by its size and beauty. It has a realistic feel but a very ethereal appearance.

It does not make a good G spotter, it was designed for girth, it does not vibrate, it's too soft to be used as a weapon, and too floppy to stand up on your bookshelf. It's form and function are quite perfect for what it was intended (even though there is a disclaimer on the bottom of the box that says "for novelty use only", and a proclamation on the side of the box "healthy for the body").

The size and plushness make it a great toy. Although harness compatible, it sagged like a monster soft pack. It won't stick to wet surfaces, so suction is out. The base is flat, but the O2 revolution is too soft and heavy to stand up. It's the cream puff of the dildo world.

What I enjoyed most was its texture and its juiciness. It had a realistic feel.

You can boil it, you can use a ten percent bleach solution, it is top shelf dishwasher safe, or you can use anti-bacterial liquid soap or toy cleaner. If you are using a condom, buy the largest size, and store it separately from other silicone toys. Only use water based lubes on this product, (unless you have a condom on it). If you don't have sharp finger nails, or jagged cock rings on the dildo, it should last a lifetime and not age a day.

O2 Revolution was in Tantus' usual form of packaging, a clear plastic cube. The word Silicone was the largest print on the box, and the box afforded a three dimensional view of the product from top to bottom. It also proclaimed "Feels like the real deal - dual density Pureskin". There were no package inserts, instructional pamphlets or samples of lube.

The website www.tantusinc.com was included on the package, and the address of the manufacturer (always makes me feel good when I see people who stand behind their products and let you contact them).

I am unable to try this toy anally. I prefer to use it manually, than on a harness. It is also hard to use on a partner because of the "floppiness" factor.
