This is a great attachment for the Hitachi. I have read that it is able to attach to other ball massagers, but I own the Hitachi, so my views will be on the Hitachi with the G-Plus attachment. The G-Plus is made to not only be inserted but to also stimulate the clitoris. This attachment would be great for anyone who wants to accessorize their toy. This toy is easy to clean, but due to the TPR rubber, you would not want to share or use this toy in different areas. I do not believe that a condom would fit this attachment due to its rather large size and odd shape.

Right out of the plastic box that houses the G-Plus, you will notice a slight smell. It is not unpleasant and not overwhelming, but a smell is present. After the first initial wash with antibacterial soap and water, the smell had dissipated. The material is extremely smooth and very flimsy feeling, which was an initial worry of mine. There was no taste other than getting a few fuzzies from the washcloth I had used to dry the G-Plus after the first bath. The G-Plus is good at picking up little pieces of lint everywhere, so I suggest using a storage bag to keep it nice after each cleaning.

The attachment has a rounded hole to place the Hitachi head inside. I like that there is a ridge going around to help fit the attachment snugly into place. I have used this attachment for long periods of time with lube, and have not seen the attachment slip or move in anyway. With a six-inch length, only four inches are insertable. You have one insertable arm that is four inches, and then, closer to the head, is another arm that is around two inches. The larger arm has a slightly larger end at three inches to help stimulate the G-spot. The smaller arm is to stimulate the clitoris.

This attachment was just what I needed to make a wonderful toy even better. The Hitachi with all its power made insertable—what more could a girl ask for? As my review on the Hitachi says, the sounds this toy makes reminds me of a blender. Add the attachment and the sounds change—and not always for the better. Just with the attachment on and inserted, the noise was decreased slightly. I found holding the toy close to my body made the vibration noise louder and more thudding. This noise was worth all the enjoyment this placement allowed me.

This attachment is great to clean. Just remove from the Hitachi before cleaning. It is able to be completely submerged and cleaned with antibacterial soap and water. Just remember, as I stated above, that this attachment is a lint collector.

The G-Plus attachment comes in a clear plastic box that makes the G-Plus look as if it were floating. I really liked the packaging. It also includes a small paper with instructions on use and cleaning.

I really had my worries about this attachment when I found out just how mushy the material was to the touch. Insertion was a little more tricky due to the material's give, but once it was in, the worries I had disappeared. The vibrations felt wonderful throughout the entire attachment. The only complaint I have is that the clitoral arm seemed to move all over the place, and yet it did not put any real pressure on the clitoris. I expressed my concerns to my husband, and he used his fingers to press the arm directly onto my clitoris. This worked perfectly. I was able to feel the vibrations inside as well as on my clitoris. I am not one of those who orgasm from the thrusting motion of a toy. We inserted the G-Plus and pushed the ball head up to give a little extra vibration and pressure to the clitoris. It was just enough Hitachi power and also a nice fullness to be able to make me orgasm.
