Second, the temperature can be raised or lowered, but it's limited to keep it from accidentally scalding. Third, length, girth, and curve can be changed as well depending on preference. Last, but not least, it does vibrate.

More on how to utilize these functions and the Chroma consumption is provided on the directions inside the box.
