The motor provides powerful vibrations in the base of the toy. However, as the vibrations do not travel well through the material and the motor is only located in the base, vibrations of any desirable strength are only attainable through pressing the base against your clitoris. This actually works quite well for external stimulation, as the toy is covered in a soft material (which I prefer to pushing hard plastic onto sensitive areas).

The shaft is incredibly small (slightly shorter and much thinner than an average man's flaccid penis), which makes it unsatisfying and pointless for insertion. However, as the shaft is completely flexible, it can contour to the exterior of your body as you press the butterfly/base against your clitoris. Also, because of its modest size and the high-quality material that doesn't harbor bacteria, the shaft is a good starting point for someone interested in anal play but hesitant to insert a larger toy.

The toy had three levels of vibration and six patterns of vibration. I pretty much exclusively used the highest vibration level, as I found the patterns to have too many pauses and the lower vibration levels to be weak. A problem with the toy is that it only has one button, so to shut it off or change to a different pattern, you have to repeatedly press the same button to land on your desired setting. This seems like a finicky complaint, but when you're on the verge of orgasm, the last thing you want to worry about is counting how many times you've pressed the button as you seek for your preferred pattern.

The toy is made with a high-quality coating, is waterproof for easy cleaning and shower play, and takes an easy to obtain type of battery... owning the butterfly is a breeze!
