The Rose Vibrator is ergonomically designed, very comfortable to hold and operate, and comes with a USB connection. It also has an LED indicator light that lets you know when it's charging or powered up.The first thing I noticed about this vibrator was how smooth the material felt between my fingers as I held it in my hand! It's made from medical-grade silicone which means it's hypoallergenic, phthalate free, odorless and body safe (you can wash it with soap).This is an extremely high-tech rosebud vibrator so no one will hear what you're doing unless they are standing right outside the door listening for signs of life from inside your bedroom!
