Firstly, I love the design; it looks like a spartan helmet, and it’s also a great design for masturbation and couples play. Secondly, this material is my favorite - it’s really easy to clean, and the helmet sides are easy to push down when you need more pressure. I used this on my boyfriend, and he said it was the best hand job of his life. He came so fast that I was pleasantly surprised. I love that the helmet is rechargeable and has different vibration settings. I started at a low setting and slowly increased the vibration speed, and he loved it, definitely bringing this back out tonight
