Honestly, I wanted this just because it looks so pretty—much prettier in person than in pictures. She's like a pet glass snake you can keep in the garden with you, eating apples and lazing about while philosophizing about life and the knowledge contained therein. And she does contain many knowledgeable lessons.
I took past reviewers' advice and started using this with the Puff after a few solo runs without external clitoral stimulation, and I've never felt a more intense, pleasurable sensation before. Now I know how supernovas are really formed. Stellar hits exactly where it needs to inside so you can stroke the internal part of your clit while stimulating the external at the same time, if desired. Talk about launching into outer space. The entire journey from start to finish is like transporting to another world.
The Puff on it's own? Amazing as an intro/beginner clit sucking device. Stellar on it's own? Amazing as a small internal exploration device, both vaginally and anally. Put them together and your next orgasm will birth a new galaxy from the intensity of your explosion.
Unfortunately, Stellar isn't unbreakable. While using her in the shower, I pulled her out and she accidentally slipped from my fingers. The tail broke off when she hit the tiled floor. So I'm back to get a new one. A friend gifted me another glass dildo with dual heads, but it doesn't stroke the internal clit/g-spot like Stellar does.
