As a rabbit vibrator this toy is designed to be used vaginally for g-spot stimulation, with the bunny on your clitoris. That being said, the tip is quite a bit wider than most toys of this type and might not be the best for beginners or those who like slimmer toys. It is best to be warmed up a bit before using this, or well-lubed.
The Couture Collection Utopia does have an O-ring and works fine in the shower, but I would be a bit hesitant to fully submerge it in the tub.

This toy is made from surgical grade silicone and is latex free, phthalates free, non-porous, and hypoallergenic. There was no smell to the material, even fresh out of the box.
The material has a very nice smooth and somewhat velvety texture, which adds a bit of drag and tug against the skin. The smooth texture means you don't need much lube and the drag and tug sensation is not really noticeable with lube. It is softer and more squishy than a lot of silicone toys and does have some give to it, so it is comfortable in your body even when clenching.

It is a pretty light pink color with a silver control base, and has a rabbit for clitoral stimulation. It is not exactly discreet looking (it is obvious that it is a sex toy), but it is designed to look more sophisticated than your typical penis-shaped toy. The tip is rounded and the widest point is maybe an inch down, and it may be a bit wide for some if they aren't warmed up for it. It does taper down in size so that it is a little thinner by the rabbit. The rabbit is fairly flexible away from the base and soft so it is not uncomfortable. The rabbit is also long enough that you can position the rabbit at your clit easily. The toy measures 10 1/2 in. in length with 5 1/4 insertable. It has a circumference of 5 in., and it is more of an oval shape than totally round at the widest point. I measured it to be 1 3/4 in. in diameter across at the widest point, with 1 1/2 in. in the other direction at the same point. The picture from a top view helps illustrate this a little better.

To open the battery compartment you twist the bottom slightly, and it pops off easily. There is a battery harness that holds 3 AAs. There are 3 control buttons that light up. The bottom is a dedicated on/off button, the middle button is for the vibration of the rabbit, and the top one is for the rotation. Having both functions on at once does reduce the vibration some, but not much. Compared to a lot of rabbits I have had, the difference is barely noticeable. This is a powerful toy and while the vibrations may not be AS strong as some toys, it is still more than enough for me (and I like my vibration pretty strong). There are three levels of rotation speed, and 7 settings of vibration. The vibration settings start with steady vibration with low, medium, and then high. Then it goes on to patterns with 4 different pattern types. I also had no problems with the rotation stopping or being interrupted while clenching, as does happen with some rabbit vibes. It slows a little, but not enough that it is very noticeable if you aren't watching for it.

There is a small clear o-ring just inside the compartment. It is waterproof and has worked fine in the shower for me, but I would not try to submerse it. It is somewhat of a battery guzzler, but I use rechargeables and always take my batteries out of my toys when not in use, so I can't say exactly how bad it is.

It's important to stay away from silicone lubricants with this product, since it will cause the silicone of the toy to break down. Only use the Couture Collection Utopia with water-based lubes. With how smooth the material is, you will not need a lot of lube. Also, even though it is waterproof, only the insertable portion is made of silicone and it is not safe to boil or put in the dishwasher. That being said, I recommend using condoms with the toy if you plan on sharing.
It's easy to clean with simple soap and water or toy cleaner works well. It being waterproof makes it so you don't even have to worry about the control portion of the toy when cleaning.

The packaging is a white cardboard box with a picture of the toy and some streaming water on it. The top flap opens up (much like computer game boxes do to show more pictures) and inside there is a clear window of plastic to see the toy through, though the toy itself comes wrapped so you can't actually see it. The lettering used to describe the product is more elegant than many products use, and overall I felt it looked kind of classy. I would not recommend using the packaging for storage, as it is just simple cardboard and plastic.

Like a lot of plush silicone toys it is a bit of a lint collector, but is not too bad. Cleaning is easy, so this is not a problem. While my first experience with this toy was a bit frustrating, all my following ones have been amazing. The shape is not perfect for everyone, but pretty close for me. I do prefer my toys to have some girth, but am not a size queen by any means. The only thing I would really change would be to make the shaft a tiny bit shorter for comfort.

I was very excited when I finally got this toy in the mail, and had to wash it up and give it a try. I love this toy, and have come to like it more and more with each use. However, the first time I used it I was disappointed, because I had expected it to work like all my other rabbit toys I've tried in the past. It does not have beads like a lot of rabbits, and while the internal rotation is powerful I noticed it a little less without the beads. Also, while the rabbit is flexible, there was a bit of a learning curve to get it positioned on my clit right, but I do sometimes have that problem with rabbits at first. For me most rabbits mean a very quick orgasm, followed by multiples. They are the go-to toy when I can't take my time with it. The Utopia did not work that way, and while I did get off the first time, I was frustrated that it took a while.
The second time I tried this one I went in with the mind that I was going to take it slow and really test drive this thing. Wow. It did take a little longer to work up to an orgasm, but it was intense! Multiples followed easily. My experiences with it since then have been similar, a slower build-up (compared to most rabbits, but takes about the same amount of time as most other toys for me), and an intense, deep O.
