I would go with the Siri or even the Mimi if I were you. The curve has an amazing shape, but it's not great quality and the vibrations are weak and buzzy. I have both the Siri and the Mimi and they are both much stronger and much better quality. Siri is not waterproof, but Mimi is. It just depends on if you want/need that option. But...Siri's shape is a little better than Mimi. I would say save up and get one of the higher end toys and skip the curve. I am tossing mine out, that's how bad it is.
