As I got my bag from the car I heard the vibrations, unfortunately so did the elderly lady tending the bushes of the local car park and innocently exclaimed is that somebodys phone? As I dived to the bottom of my bag to turn the toy off and start the walk to our cottage hoping the toy didn't come on again. Aside from this somewhat amusing moment, this toy is loud and wouldnt work when discretion is required, however it does hold some powerful vibrations. Unfortunately the button has meant this toy has turned off or on at inopportune moments, even during use
