This toy enhances the feel of the Hitachi. It's like make-up to a woman - it's meant to enhance the beauty that's already there. Well the toy attachment is the make-up and the Hitachi's the woman and boy does it enhance! My husband uses it to help stimulate my G-Spot - and it works fantastic. You can also use it as a tease or foreplay toy by gently massaging the outside of your vagina and clitoris (with or without the Hitachi). This toy attachment works great for anyone who is adventurous enough to buy the Hitachi - beginner or advanced user - neither one will be disappointed!

The material for this attachment is a smooth silicone. It's non-porous, phthalates free, hypo-allergenic, and latex free. It has a slight rubbery smell, but nothing too noticeable. I like the smooth surface because with a little added lubrication it feels so good going in and out of the vagina. And I think the smooth surface also aids when using this attachment with beginners because they do not have ridges to contend with. The material of the attachment is very durable and somewhat flexible - so it does give a bit (like a natural penis) while in use. Beginners and more advanced users will love it!

The design, size, and shape is great. It's smooth and sexy. The shape works well - it hits the G-Spot just right. I have average sized hands and it fits in my hand perfect from fingertip to the base of my palm. Advanced users would love the size but a beginner would love it even better - because I find it doesn't go in too shallow or too deep (just right).

If you feel comfortable traveling with the Hitachi - then traveling with Jollies Curved Hitachi attachment would be okay too (since they go hand in hand.) But keep in mind the Hitachi is loud (with or with the attachment) - but certainly both are worth the investment!

I would rate this attachment extremely high for performance! The vibrations go through the Hitachi and extended vibrations throughout the attachment - but seem to be directed towards the tip for extra stimulation. My husband and I use this sometimes as foreplay to encourage the mood or to extra stimulate with sex as the end goal, stimulate the G-Spot over and over to encourage squirting, or simply to coax an amazing orgasm. It works amazing for all those purposes.

The curved attachment simply pops on the Hitachi and I find to get it off - twist as you pull up (so as to not damage the Hitachi). This toy attachment is not noisy - the Hitachi is though. It is waterproof - but the Hitachi is not. Please keep that in mind when using.

The care and maintenance for this attachment is super easy. After you've popped it off the Hitachi - it cleans up in the dishwasher, a boiling pot, or in bleach. It's extremely durable and can be stored very easily. My husband and I store it in a bag with the rest of our sex toys.
