I think the Fun Factory thrusting more than any other vibes are very much a marmite thing. People love them or they don’t. As @Calie says, they are very different to normal vibrators and are a totally different sensation. I have the Stronic Bi-fusion Thrusting Rabbit and I didn’t get on with it (though that may be much more to do with the rabbit shape not fitting me and the buzziness of the clit vibe than the thrusting which was very good.)
