I have been wondering the same thing.

My SaSi review has just been published.
To me, it doesn't simulate oral sex at all. If you want that, you're better off with the Sqweel.

SaSi is an ok toy but way over-priced and if you require a reasonable amount of clit stimulation, this may not be the best.

other than the sqweel what do you suggest?

It doesn't sound like it...

I have been looking at this for a long time!!

I believe this is a good little machine, the only real downside for me was that.. I -=love=- attention like this thing gives. I don't tire of it.. but this little thing gets really hot, and down there it starts to get a little irritating for it.. but it feels so good you don't want to remove it. The vibe is built solid, meaning it doesn't feel cheap. It does make a little noise but under the covers you can't really hear it. Now if the manufacturer is telling you NOT to use it under the covers, then you'll most likely be heard using it if anyone is outside your door, or in the next room if your door was like mine at the time - a pair of french doors with open slats. The plug cover that seals to keep moisture out, is also hard to pry up to insert the extra thin charging plug that goes into it. But those are things that I think once you get the hang of, is a moot point. It's a quality built toy. Those, usually cost more.
