Use:
The Couture Collection Utopia is another great, high-quality rabbit vibrator by Cal Exotics. It's a dual-stimulation vibrator with tickling rabbit ears for external stimulation and a large, rotating shaft for internal stimulation. This vibrator operates on three AA batteries (not included) that go into the battery pack at the base of the toy. The battery pack is easy to access and the batteries are simple to install. This toy can be used for both solo and partner play, and the fact that it is waterproof means it can be used nearly anywhere.
I, personally, do not use vibes anally, but I would think this one would be great for that since there's no change of anything getting lost because of its size.

Material/ Texture:
The Couture Collection Utopia is made of sleek, smooth, medical grade silicone. This high-quality material is odorless, non-porous and repels dirt and bacteria. It is still important to use a condom with this toy if you are sharing with a partner. Also, it is best to use a water-based lube with this one.
The shaft, itself, is smooth with two subtle ridges. While this toy doesn't really feel like a real penis, it does have some give to it.

Design/ Shape/ Size:
Overall Length: 10 1/2"
Insertable length: 5 1/4"
Circumference: 5"
Diameter: 1 5/8"

Between the length and girth of this toy, it is probably not the best for beginners. The shaft gets wider towards the tip, providing a wonderful fullness that feels so good! There is enough stiffness to withstand plenty of thrusting, or you can just sit back, relax and let the vibe do all of the work.

Functions/ Performance/ Controls:
This is a multifunction, multispeed waterproof vibe that provides dual stimulation through the shaft and clitoral attachment. The rotating shaft on this toy is supposed to have three speeds, which are controlled by the top button on the control pack. However, I found that, once the toy is inserted, there is little to no rotating and only a small vibration is felt. The clitoral attachment has seven functions that include three levels of vibrations along with pulsations and escalation combinations. The clitoral vibrations are strong and intense. Even the lowest setting may be too strong for some.
The controls are easy to use unless you want to turn the rotation on. Although there is a designated button for the rotation, it will only turn on once you go through all of the functions on the clitoral attachment. It's very confusing and I still have not quite figured it out. However, if you aren't going to bother with the rotation setting, the controls for the rabbit ears are easy to use. The other downside to the control pack is the shape of the base and cap. There is not a flat surface at the base, so for those that use multiple toys, or switch back and forth from toy to partner, this makes it difficult to set the vibe aside and keep it upright and clean. Obviously this is not a huge deal, but it can be somewhat annoying at times.

Care & Maintenance:
This vibrator is simple to clean since there is little texture on the shaft. The bunny stimulator is a little more difficult to clean because of the small crevices, but it's such a small area that cleaning is a super-fast process. Because it is made of silicone, you can use soap and warm water, or your favorite toy cleaner to disinfect. It doesn't collect lint or show signs of wear after cleaning either, so you can store it pretty much anywhere.

Packaging:
The Couture Utopia comes in a nice, white cardboard package. There is a cover flap that opens like a book, while a plastic film covers the toy itself.

Even without the rotating shaft, I still love this toy. The quality is evident and the combination of the shaft size and strong clitoral vibrations is right on point to give me amazing orgasms.

The quality of this toy has proven itself to be extremely high and durable. It works just as well now as it did the first time, and it has had many many uses.
