Hmmm… missed one, mostly because I could not decypher what exactly it was or how someone would use it, until I went to the manufacturer’s website and could then see it from different angles and see how it was supposed to function.
It looks downright painful. That kind of range of movement(including changing angles) looks like it would not be good at all. A tear of the perenium seems the most likely result of an enthusiastic session. Hopefully you can make smaller rocking movements and get decent stimulation still, but I’m not sure how it would work. It looks like the neutral position is all the way down and you’d have to rock between full and half(never going below half, so always keeping tension on your muscles). It just doesn’t look like fun.
The Sybian, on the other hand, seems a little too easy. What fun is it if you don’t even have to work for it?
