Before I start on the [USE] part of the review, I'd like to tell you how the O2 Cush arrived - in a plain cardboard box, with no markings/logos or anything that could give away what was inside. Once I opened the box, I found the O2 Cush nestled inside a lot of cushioning (no pun intended) brown paper and the receipt of course. The toy arrived in a transparent plastic box, through which you could easily see it, so if you're planning on gifting it to someone, you may want to invest in a gift bag or some nice wrapping paper to do so.

Below you'll find it compared to a standard Rubik's Cube.


[ USE ]
This toy feels like it was designed specifically for size queens.

The only way I can imagine using this toy on myself is vaginally. Despite being 1 3/4" in diameter & dual-density, the silicone isn't very forgiving - in other words, it's not as soft or cushion-y as I would have hoped it would be. I can picture size queens gushing over it both vaginally and anally, but I'm no size queen. The toy itself can be used with manual trusting or with a standard o-ring harness, but, unfortunately, I don't have one of those to test it with, so my review is based on manual thrusting alone.

Looks may be deceiving -- the base is not a suction cup; it cannot and will not stick to flat surfaces. If you're looking for something like that, and insist on the O2 Cush, you may want to pair it with a harness and strap that around a chair of some sorts. The tip of the toy is slightly pointed. Unlike my other toys, when in use, that pointed tip feels very strange, to say the least, and I'm not sure if I like it or not at this point. Despite using excessive amounts of lubrication and spending a lot of time 'warming up', I cannot take the entirety of O2 Cush yet. I can take other toys that are 1 3/4" without issue, but with O2 Cush, it's a rough ride. I can get a bit past the ridge that's about midway, and because the material isn't very soft, it's more of an annoyance than something pleasant when it rubs against me internally.

The silicone has no smell, taste, or odd residue. It's got a matte finish and acts like a dust/lint/hair magnet.
The material itself used in this toy is lovely; however, despite being advertised as 'dual density', I can't feel that dual density while it's inside me. I can somewhat feel it when I squeeze it with my hands, but when I squeeze it with my vagina, I'm rather disappointed. I have a fondness for squishy exteriors, and was expecting something softer for the outer layer - frankly, it was the only reason why I invested in O2 Cush. I cannot bend this toy in half - it's too firm for that. I've seen other reviewers post photos of bending it halfway, but I'm concerned that it'll split if I do. If you're hoping for something like VixSkin-softness, this is not it.

Because of its size and lack of squishy-ness, I'll have to recommend this toy only for size queens and advanced users. Beginners should reconsider when they have more experience under their belt, as it can and will be a painful experience for those that aren't prepared. I believe this will easily apply for those that want to use this toy anally as well.

In theory, this design appealed to me for months on end. I was turned on by the sheer idea of its shape and curves. Now, after using it a few times, I'm just flat out disappointed. I'm no size queen, and although I have toys in this size (and bigger, actually), this one just feels too big because it doesn't have varying diameters. Other dildos have a gradual increase in diameter, where it gets wider the further you take it in - with the O2 Cush, it's almost-instantly at its thickest point, and it stays thick.

As mentioned before, I was expecting a plushness from the dual density, but it's almost negligible when in actual use. I like dual-density toys because I can squeeze them with my vaginal muscles and feel the inner core. Not with this toy. I can squeeze and squeeze and squeeze, and it all feels the same to me. The ridge at the midpoint, which is supposed to stimulate the G-Spot doesn't reach my G-Spot as the toy is too firm to bend in the G-Spot's direction. I just feel as if I were trying to stick a log up my vagina, and that idea usually doesn't turn me on.

I tried to appeal to the fetish/concept of filling myself with a girthier toy and then a smaller one, to see if the loose-ness would be pleasant, and I felt no difference in that.

On paper, this toy is a wet dream come true. For me, in reality, it really isn't. As mentioned in previous parts of this review, I was deeply hoping for a more squishy dual-density toy - I was basically hoping for something like VixSkin Mustang but bigger and more aesthetically pleasing. The size is rather large, and because it's not very squishy, you will feel very full very quickly.

Tantus advertises this silicone as "100% Ultra-Premium Silicone". O2 Cush's got a matte finish, so it'll attract your hair, dust, and lint like how my milkshakes bring boys to the yard. Regardless, one should always see to cleaning this toy before and after each use - I stick to hot water and soap, but you're welcome to boil (3min), bleach (1:10 bleach to water ratio), leave it in the top rack of your dishwasher (no detergent), or use your favorite toy cleaner to get the job done.

The transparent box it came in isn't good for storage, as it's flimsy and easily flops open; there's no included storage pouch. I just keep it in one of my spare EdenFantasys pouches for now. There was minimal information on the box describing the material, size, and Tantus itself.

I've used O2 Cush a handful of times prior to writing this review, and even with all the hype I've built around it before getting it (with reading other reviewers' steamy reviews, watching videos about it, and just anticipating its arrival), I was mostly disappointed. I've had an adequate warm-up, plenty of lubrication, and took things slow. It feels a lot more firm than I hyped myself up for. I truly recommend this toy for Size Queens or Advanced users - else, you may end up disappointed like myself.
