The O2 Revolution from Tantus is an amazing G-spotting dildo. The dual-density silicone is plush feeling, yet firm enough to give just the right amount of stimulation. It can be used as a traditional dildo or put in your favorite harness. The squishiness of the O2 material is perfect for vaginal or anal play. Due to the larger size of the head, it may not be appropriate for everybody.

I just can't get over how amazing the O2 silicone feels. I can sit here and squeeze it and run my fingers over the velvety head and shaft for what seems like hours and not get bored. It has no smell or taste. The veins are more for looks than texture.

The O2 Revolution is dual-density, meaning that it has a thinner, yet firm inner shaft and a thicker, velvety soft outer layer. The silicone is firm, soft, slightly stretchy, and is pretty flexible. Tantus toys are made from ultra-premium, platinum silicone which is the finest material found in the toy market. It is hypoallergenic, phthalate free, boilable, bleachable, and healthy for your body.

The O2 Revolution may be too large for some. It is 7 1/2 inches long and has a 1 3/4 thick head. The base of the shaft is only 1 1/2 inches thick. The design is semi-realistic with a very unproportioned head. The head is much larger than anything I've seen in real life or in porn, but it feels amazingly soft. It is the best thing about this dildo.

It has a slight curve and a thinner shaft. The base is flared slightly and you can see where the outer milky white layer of silicone fades into the hard inner neon pink core. The candy colors of the O2 Revolution and comically large head and veins make this perfect for those that don't like realistic toys.

The O2 Revolution, or Mr. Pink as he is lovingly referred to, is the only toy that has managed to get me to come from vaginal penetration alone. The large, soft head and the slight drag from the silicone feel amazing on my G-spot. It is firm enough to give the pressure needed without feeling uncomfortable like some G-spot toys.

The thickness of this toy made anal difficult at first. I found that I needed to warm up with another toy first before being able to use Mr. Pink. His size may make him a little intimidating for some for both vaginal and anal play, but it was worth it.

I haven't gotten to put him in my harness yet. My boyfriend thinks Mr. Pink is scary and won't let me come within five feet if I'm holding it.

Tantus toys are very easy to take care of and have the possibility of lasting a lifetime. These hardy silicone toys can be cleaned in a variety of ways. The O2 Revolution can be boiled, thrown in the dishwasher, cleaned with a 10% bleach solution, anti-bacterial toy cleaner or wipes, or plain old soap and water.

It is a lint magnet, so washing before and after use is best. Store your Revolution in a cloth bag, a Ziploc bag, sock, or whatever you want to keep it away from other toys because it can get stained. My Mr. Pink now has "freckles" near the base of the shaft from leaning against a darker toy on wash day.

The O2 Revolution works best with water-based lubricants and isn't meant for use with silicone-based lubes because they can ruin your toy.

The O2 Revolution came packaged in a clear plastic clam shell and larger clear plastic box. The package tells a little about the grade of silicone used for Tantus toys, general care and cleaning tips, and that it was hand-made in the United States.

The plastic box is too flimsy for storage, so it was tossed in with the recycleables.

This is my favorite dildo. It will be hard to replace or one-up. The size, shape, and cushiness of the O2 Revolution make it perfect in my book. It is one of the only dildos to have given me G-spot orgasms AND made me squirt.

I'm thinking about trying some of the other O2 toys by Tantus just because I love the feel of the duel-density silicone.
