The Hitachi is my favorite toy of all time, so I was really excited to find an addition that could actually penetrate and is much easier to put on and take-off of the wand than another attachment I have purchased elsewhere. And this one has even more options too! It can penetrate both holes as well as tease the front all at once. I also love the intensity, and you can't really get much stronger than this. The texture is a little weird and not very forgiving in the squish department, but sometimes people like it stiffer. Super easy to clean too.
