I've traveled with mine without any issues, but a young woman sitting by me on Amtrak once opened her travel bag , and the " battery operated magic wand " turned itself on . It was very loud. Everyone on the train was wondering where the noise came from.  
I looked at her and smiled!  
 

A wonderful client gifted me one and I use it often alone. I've pulled it out a couple times during sessions but I typically don't need to pull out any toys for myself during a meeting.  

But boy oh boy that hitachi is very worth it and irreplaceable!!

It's the only toy that can always make me squirt!

At my side table at all times

My favorite toy!  Sleeve attachments for the boys too!
