I just reviewed this and I really love it! I would have to say the functions are probably the same as all the other OhMiBod products. What differs is the vibrator style you prefer. If you like traditional vibes go withe Freestyle. If you like clitoral vibes go with the Better Than Chocolate. Finally, if you like G Spot vibes, go with the Freestyle G. It really just depends on the style you like. As for the price... you get a splash proof, body safe, music enabled, rechargeable toy that is whisper quiet and packed with function. The price is worth what you get.
