I love the Ina. It's a very powerful rabbit type vibe.
I have the Gigi, the Ella, and the Siri. All of them are SO amazing. Right now I am pulling out the Ella most often because I just got a new roommate and even though Lelo toys are very quiet, I am still not going to chance it just yet.
I have: Iris, Isla, Alia, Mia, Luna Beads, Siri, Lyla and Gigi.
I think my favourite all round would have to be Iris. Gigi would be great if it was longer so I had more damn handle to hold. But I keep accidentally pushing the damn pattern button while in use which totally frustrates me.
