Up until now, I had been using two toys at once for double penetration, but this is a lot easier to use. It’s perfect for my arthritis, so I don’t have to hurt both of my hands. The glass is of good quality and sturdy. Solid glass, so you don’t have to worry about it breaking easily. I love the texture on the one that is inserted anally. It feels like a slight vibration going in and out of my asshole. If left at room temp, it’s a little cool, so it’s nice for a different feel. You can also put it in the fridge if you want it extra cold.
