I have the OhMiBod G, and I would like to invest in the Freestyle.
If you love music a lot, it's definitely worth it.
Otherwise, the vibrations without the connectors are meh.
I think they are only worth it if you're really into listening to music. Otherwise there are far better shaped vibes.
I have the Freestyle and have only used it twice in the year I've had it. So to me, not worth it.
I have the original one and don't think it's worth it. The vibrations are really weak. For stronger vibs, you have to turn your music up really loud - too loud.
