Good vibrations indeed! I'm a beginner when it comes to anal play and I was unsure if I'd like it or if the bulbs on this toy would be too big. They ended up being a perfect size for me- no discomfort, and just enough to feel a little bit full! The vibration packs some good power (takes AAA batteries), with different speeds to choose from. I'm definitely not sorry I bought things. Cute, sparkly, easy to clean and easy to remove!
