My Cadejo just arrived today and I have to say I'm very pleased. I have a Cerberus and while it is a good toy it leaves a bit to be desired. Cadejo is firmer than Cerberus and the knot is a lot bigger and more natural looking. I also like how smooth it is, Cerberus has (or had mine's four years old) a rough texture on the surface.
One other thing I notice missing from a lot of reviews is real-world sizing. I'm right at 6 inches long and the large size fits me perfectly. (not to fault Fetishzone for any reason, I just find it helps when someone says their size and how things fit).
