The Freestyle is unique from any other vibrator on the market because it sync's with your iPod, stereo or pretty much anything else that put's out sound. Enjoying your very own playlist inside of you is just an amazing feeling! A definite plus to the Freestyle is that it's rechargeable, wireless, and also has a manual setting in case you want to use it music-free. You can turn up the volume to make it stronger, and turn it down to get slower vibrations.
