A Closer Look
You will find two buttons near the end: the first with the pretty power logo turns on the vibrator. You can now switch through the patterns by pressing the waveform button.
When switched on, the vibrator will not move immediately; it will just turn on a red LED, which gives the button area a nice glow that also helps with orientation in a dark room.
Batteries (2x AAA) are inserted into the back compartment after the cover is removed by turning and pulling. I find it a bit difficult to open and close, especially with long fingernails.
We've also disassembled the vibrator to give you a view of its insides. It is a really simple construction with the motor at one end and the battery and controls at the other. The white piece in the middle is just some foam that helps with the vibrator's flexibility while protecting the cable from damage due to vibration.
