I have Ella and Olga, and like them both pretty well (they're both 3.5 star toys, I think).
I had the Ina and I hated it because the internal motor was too weak and my kegels could stop it. It wasn't waterproof, either
I also have the new Smart Wand Medium and it's my favorite Lelo toy so far. I love that it doesn't numb my hands, it's waterproof, the angle is great, you can apply pressure without losing power... 4.5 stars so far I think (but I need to test it more
