I have tried two from the first line (Kiki and Honi) and they both sucked pretty badly. I also have the new Zizo which is just awesome! The new line is actually a lot better than the first one, and the designs seem much more well thought out.

They are not going to be as strong or quality as the Lelo toys. They aren't rechargeable, but in turn they are waterproof. I recall that there are several reviews with comparison images, so you may want to focus on the shape differences between Picobong and Lelo if the power and different features don't make up your mind.
