The material is silicone. This means no smell, and it's silky to the touch. Of course this only applies to the head of the rabbit, as the main body is simply plastic, or ABS. The silky feel of the rabbit does add some stimulation, and the little bumps of his face can be manipulated against your skin for additional pleasure. There is no real user that this texture wouldn't be for, as it is fairly basic and simple in design.
The design is one geared towards cuteness, I would think. The simple color and rabbit's-head-look lean heavily in this regard. The ears are flexible and can be used in a number of interesting ways. Overall, the shape of it is very nice when fit into one's hand. In terms of size, it is a bit larger than a battery-operated hair trimmer, so it's easy to pack away and take with you. It can be hidden fairly well due to its size, and could easily be slipped into a pocket.
The controls of this item are fairly simple to master. One button turns it on; the other cycles through the vibrations. I don't think there is an easier control scheme out there than this one, so it's great for a beginner to this type of thing. Sadly, the vibrations were mainly focused on the portion of the Embrace that you hold. The rabbit's head itself is seemingly a solid piece of silicone.
That isn't to say that the rabbit portion doesn't receive vibrations. It does; even the ears can make you tingle. But the vibration motor itself is firmly in the base, so the bulk of the vibration is there. The toy is waterproof and will continue to vibrate when submerged, thanks to a rubber/silicone gasket to protect the mechanical workings in the base. However, a few drops of water do make it into the area outside the gasket.
For sound, the vibrating can be loud if in the same room as you, but behind closed doors it isn't really as noticeable, which is a good thing. The types of vibration vary from a constant vibration to pulses that send the vibration to you in waves. This means the noise level can vary, though at its loudest you still shouldn't be heard from behind a closed door, unless you were fairly close to the door itself.
As with any sex toy, you need to wash this one before and after every use, though I think most people just settle for a cleanup after the fact. Since it is waterproof, you can just toss it into the sink with some soap and hot water, or you can use a preferred toy cleaner that works with silicone.
To store it, I would tend to favor the box it came in. It's simple and clean overall, without having to worry about it coming into contact with another toy and sparking off a bad reaction. Somewhere cool and dry, without an abundance of heat, is generally a good idea as well.
For lubrication, you want to stick with only saliva or water-based types. Don't use silicone-based lube here, as that is a bad thing for silicone toys.
The toy comes in a clear plastic box typical of a lot of toys I've come across. The main details and warnings are featured on the bottom, such as it needing a pair of AAA batteries (which aren't included), to clean it before and after each use, and to only use water-based lubricants. The back is strictly for information, in multiple languages. It talks about the buttons, functions, and feel of the toy itself.
For my part, this is an average toy for stimulation. I would have liked it better if the rabbit had more vibration than the body. It seems like a bit of a design flaw to me. Those two ears would have been great for a higher level of vibration. I can only imagine how it would feel to have one of those on either side of a clitoris, acting like a tuning fork. On a positive note, one could also hold the rabbit and insert the base for a bit more vibration and stimulation, though I wouldn't recommend that in an anal capacity.
