Review on Nirvana Sailor Portable Anti Attack Emergency by Johnny Snyder

I first bought it for my daughter hoping it would give her some security when she is on the train etc. When I received it I decided to try it and see if it worked. I tried and nothing happened. I kept fiddling with it and a noise would come out from time to time. It appeared to be a piece of cheap plastic that could NEVER be relied on to work. I'm grateful it was cheap as it was useless so I threw it away.
